I am curious to see what you base this on. Sounds like a lot of hand-wavy speculation to me. If you would have talked about Americans going for American Football in college rather than say, Olympic Weightlifting, that would be a different thing. When exactly does someone like a Carlsen (Norway) or Anand (India), as "gameplayers", choose to go into a different game than chess? As an example, I used to play chess when I was younger. Plenty of people later took up things like poker and starcraft, and a few became quite successful at it. These people were generally not the best chess players, instead they were more likely to be average / slightly above average (for being serious club players) in chess.
