I think what he meant was that you can take a group of people and train them for a sport. Some of those people (genetically elite athletes) will improve very quickly with minimal training, others can do massive amounts of training and never reach beyond a certain level.

Yes, this is what I mean. It's not that talent doesn't exist, but it's never the case that people on the top of their domain work less hard than others. In fact, it's the opposite. People don't have talent, the talent has them.

Not necessarily. See George Best

Elites who put in a lot of work are world class. You can’t outwork genetics.
