Your point is not unreasonable, but I wonder if those who have infinite money will enjoy gambling as like as others? Because a person who has that much money is busy with other things. I think that even if there is evidence that those who have infinite money gamble, it will not be much. But if we talk about ordinary people who are greedy for money or have a lot of money but do not have infinity, gambling will definitely be enjoyable. There will be a fear of losing and that fear will create excitement. I enjoy gambling quite a lot. I will not say that I have become lucky in gambling, but I have a special attraction to it. Sometimes gambling is a very enjoyable way to spend my free time. If I had infinite money, this joy would not have worked in me.
Well that's if you talk in realistically, wealthy people have no time because they're keep working and improve their business, they're still gambling, but much more like to find opportunity or have a purpose to expand their relations.
In this thread isn't even make sense at all, even Elon Musk's net worth has a limit.
But I agree what with you said above, when we had infinite money and gamble it, it's similar like betting without money, not risking anything. Imagine you gamble without staking anything, is it really fun? nope.
