>It's harder to play baseball or football without all assortment of costly bats, helmets, gloves, et cetera

In practice, casual football isn't any more resource heavy than soccer. Most non-league games of football are going to be "touch football", which only requires a ball, a field, and some sort of end marker (as a kid, it was usually just "from that tree to that other tree").

Obviously, organized league play has a ton more equipment, but the sort of informal casual games that kids or young adults play requires much less. It's one of those things that doesn't really get talked about a ton compared to league play, so it's easy to miss for those who didn't grow up with it.
