I never have heard a gamer call themselves an athlete seeing how a gamer alone is anything but that
You can get an athletic visa from the U.S government if you play video games for money. These people call themselves athletes all the time, they think they are playing a real actual sport and they they are athletes.
Not all of them of course, many of them have the logic to understand they are just playing video games for some cash, but some of them fully believe they are real athletes, as does the U.S government....yeah. Our athletes are now fat slobs that spend 12 hours a day starting at a computer screen (obviously this is a generalization, but just look at that pic I posted, that guy is apparently an athlete).
