I'd bet civilian/recreational players are also a tiny minority. Depends upon where you are of course. But hard to reconcile the 'obese American' with the image of a nation of sportspeople, for instance.
They probably are a minority, but how does that relate? There are still millions of people participating in the game, having more spectators doesn't negate the participants. If anything I think that would reinforce it being a good game.
Most gamers aren't pros either.
