publishing game

Hello. my first minigames are almost ready. First person multiplayer shooter which I will try in steam,gamersgate,gog etc and other puzzle game maybe in android. So if my game sells and earn few euros. so how they usually pay steam,gamersgate, google play? do they pay to bank account or paypal account. I am student and If i get enough money from games my financial aids which i get because i study may cancelled if my revenues are too high. So that’s why i ask how the payment happened, if paypal then it is not problem
