That's actually true, some of them that are gambling are using it to pass time and socialize with friends, they already have some serious investment that they took risk to invest a significant amount of money with high chance of getting a good return but they are financially smart to know that gambling is not what they should consider as an option to put in a huge amount that they can not afford to lose, because they know that it doesn't take time to lose it all or double it, which can be way riskier than expected.
There are several very wealthy people in my circle, and I can say with great confidence that none of them gamble. At least, if they do, they keep it so well hidden that no one knows about it. I believe the main reason people start gambling is the desire to make extra money, but wealthy people simply don’t have that need. Firstly, they already have businesses that bring them income, and in most cases, it’s not just one business. They usually have several sources of income, which means they’re unlikely to seek out additional, especially risky, opportunities like gambling.
I’m saying this because if wealthy people were to get involved in gambling, there probably wouldn’t be much difference between the rich and the poor when it comes to gambling, except that the rich might place bigger bets. And in many cases, wealthy people simply don’t have time for this kind of thing.
