For some gamblers, it is about money but for some, they only play for the entertainment, therefore they are still able to play gambling even if they have an infinite amount of money. For me, I'm among those who play for the money but I think I will still play gambling even if I have an unlimited amount of money because like you said, there are plethora of games and me as only a poor gambler, I can't help but to just look at them or be jealous on other gamblers that has the capability to play at least many of them and also bet a decent amount on them.

In your case OP, maybe you are among those who play for the entertainment but saying that you don't care about the money seem still off. If you mean it, then how will you live and support your other hobbies, which I'm sure not free at all.
