That's just utilizing potential already present there and nurturing it far, the father was an established chess player and university professor and their mother is probably in similar range. Sure, it works, why would anybody argue against or find this shocking or relevatory?
Try the same with babies who are already visibly not the brightest (say in kindergarden group), their parents are also average or worse regarding intelligence. There is a ceiling, it may be high or not but its there. If you haven't experienced it in your life you are one of lucky few (and certainly didn't push yourself hard enough to sense it).
Same goes with memory - you can train it far, use various techniques. Then comes somebody natural (yet still far from what we would call genius) who didn't bother with any of that and immediately surpasses whatever was achieved. We are not created equal and all have hard boundaries, be it health, cognition, body regeneration and so on.
Data point: my comment prompted different reasons for why Polgar was successful: it’s genetic, he had time to spend with his kids, he was a professor, his kids all happened to be gifted, if you go to a kindergarten class you’ll already see kids that aren’t bright. Clearly more comfortable for explaining away because it forces us to look at why maybe we aren’t geniuses or our kids aren’t.

It’s always hard to compare how much effort and for how long they’ve been applying it between people. Someone starting earlier can make them seem like a genius. Someone who spent time developing their memory through various games may feel like they spent no time on it and “it’s natural” while someone else had to explicitly work at it instead because they never were encouraged to play memory strengthening games.

Thats true, but the same was said of height but height only became 90% genetic once we fixed nutrition. I see no indication that our systems of parenting and child rearing are robust enough to make intelligence and academic outcomes purely genetic. It’s far too chaotic and you need to apply consistent effort daily almost from birth before the intentional learning stuff even happens. Making sure the mother is in good physical shape before birth, taking all the supplements before and after birth, limiting exposure to toxic stuff, making sure the baby is getting a good mix of engaged play, time to be chill, and exercise, making sure both parents are able to keep the child engaged and studying and understanding of expectations, adjusting the environment appropriately as they develop so they’re constantly challenged and enjoy and seek out challenges, that’s it’s emotionally and psychologically safe for the child, riding the balance of a little bit of frustration and recovering from that vs no frustration or frustration without a break, etc etc etc. a bunch of that happens before you start academic play to teach verbal and math skills and each of these is an add on (eg we know physical education is important for brain development).
Data point: I was at a prenatal class and after the nurse said marijuana isn’t good for the baby, one of the parents was asking “but like what’s the actual limit before it’s harmful”. So don’t be too sure that “surely kindergarten is early enough that kids are still on equal footing”. Another data point is I know a parent that has a 4 yold that doesn’t know how to read nor write because “he’s stubborn” nor is he going to preschool. Yet every parent that I know of that’s applied effort has their child typically by 2 or 3 and writing by 4/5 which is when basic math should already be going.
Nowhere did I state that there aren’t natural limits. But I also think academic achievement isn’t 90% genetic - there’s plenty of “naturally gifted” people who go on to not achieve anywhere as near as much as those who just work - perseverance trumps almost everything and environment trumps that because that’s how you learn perseverance.
The closest to the truth for Polgar is he had time to spend with his kids, but mainly because he prioritized doing so in a way to help them grow. Also, he did so with help from his wife. He wasn’t a chess prodigy. He chose chess because there was a clear demonstratable progression that a) could be used to demonstrate his theories b) his kids had immediate feedback on success c) could repeat the game endlessly to try out various tactics d) they studied chess as a family.
I agree, not every child can become a genius. Most of the reason for that today is less because of a learning disability or “physical limits” and more because of the environment the children are raised in (and the need to teach them perseverance and to keep trying regardless of how others are achieving).

Where did you find this information? I haven't been able to find any source that states he was above an amateur level.
