This is mostly the truth among the addictive gambles you can say it. Because for those who actually play for fun would be realistic and may not play more to recover their loss and thus in this process of making profits from losses turn them to addicts.
That is why to play for fun is actually much better than playing for profit. Afterall we dont want to risk more than what we can afford that is why I dont suggest people to play for profit unless he has alot of money that he can throw. I dont really believe that the profit from gambling is for everyone to take as well
