Poor players are not very different from rich ones; here it is important to understand the main idea that you don’t need to chase big money, but enjoy even small victories. Also, the most important thing is to limit losses, because if this skill is not there, then the loss will not be long in coming, and it does not matter whether it is a poor or a rich player.
In terms of behavior, it may be the same whether the gambler is rich or poor because everyone has emotions and egos that sometimes cannot be controlled so that in the end playing goes beyond the limits, making anyone addicted to gambling and taking big risks, but in terms of mindset there is a clear difference, usually rich gamblers just want to playing gambling to have fun and just looking for entertainment, there are also those who want to make money from gambling but mostly for entertainment only, things are different from poor gamblers, usually they gamble to try their luck and want to get rich quickly from gambling, even though there are not many people who are rich and successful because of gambling except doing business.
In terms of character and behavior, each person is usually different, depending on the ego as you mentioned and also depending on the level of emotion the person has, because sometimes there are people who are very sensitive to everything that is not appropriate. with the hope that even though it is a trivial matter, or what it means is that sometimes there are people who get emotional easily even because of small things. But if we talk about the personalities that rich and poor people have then of course I think I would also agree with the opinion you, not without reason, but we can see that rich people have succeeded in bringing themselves to financial freedom in their lives, where this success is caused because they have a different mindset and way of looking at money, meaning I don't believe that rich people make gambling a place to earn, because of course before they get involved they will definitely assess first what the positive and negative sides of the activity are, meaning I am sure that it is very likely that rich people will not treat their gambling activities excessively.
While poor people I think is quite doubtful, in the sense that there is a big possibility for them to try their luck in gambling, logically they have a worrying financial situation where they lack money to meet their living needs, while as we know that gambling provides opportunities to win for all users, meaning I think it can be used as a reason that there is a big possibility that poor people will use gambling as a place to make money.
