Well this things all depends on what everyone feels about gambling and why they engage in it. Some people gamble for the money while some gamble for fun. To those who gamble for the money they might not be too interested in it because they already have enough money so why waste time to gamble but to those who play for fun doesn't matter how much they have they will always have interest in it because they are always entertained.
Personally for myself I don't think I will have any reason to gamble if have infinite amount of money.
That is, it is interesting to play if it is for fun, but you would not play if you had endless money? So you definitely play to earn money, and if you can’t make money on gambling, then maybe there is no point in doing it. I am also not sure what I would do if I had endless money, most likely I would travel a lot, and this often requires a lot of energy for other things, so even if I played, I would definitely do it much less often.
