You'd be suprised. It's not uncommon to see players that only play that much because they want to become a pro player, but in the end they never make it, or qualify to 1-2 tournaments. The lucky ones end up making money from streaming, but a lot depend on their parents or girlfriend's for a place to live since they don't make enough money to live off of.
I think we are talking about two very different things. I am talking about bus ticket collectors and you are talking about gamers playing pro games giving millions of dollars in prizes.
edit: I re-read my previous comment and I am not sure I could make it more clear.
if a game does not gives money prizes at all, the ones who are playing it are not playing for the money.
