The factor of circumstances and weak finances in real life is the biggest driver that makes them always chase victory and do not care how much money they sacrifice, actually what they do is not a struggle to achieve a big win but slowly if you or they realize the facts that occur are actions and goals like that only throw their money drained slowly and without realizing it, the more they are surprised by the amount they lose a lot then another possibility or another decision that seems more likely they will choose to act more aggressively because of the inability to accept the risks that occur.
In fact there will never be a better situation if you have that perspective on gambling, simply put when you lose you will be curious and when you win you will be addicted, so it's actually a cycle for people who are already into addiction. For the rich themselves it obviously seems to be true that a good financial situation will not make them act excessively, the logic is as you said that by having many sources of income then obviously at first glance I already know that most likely they come just to fill their empty time along with seeking entertainment, while the poor have a purpose that is not recommended, as I said that the situation factor is the cause.
If they don't pay attention to their lives and only care about gambling because they want to chase more wins, they will only experience greater disappointment because they will probably experience greater losses. They have wasted their money even though if they used the money to meet their daily needs, they would not lack anything. But because they saw that several people could win, they were interested and wanted to try it. That is why we may still often see many people who experience losses from gambling and cannot control themselves while gambling until their money runs out.
In fact, with self-control, we will not become curious and want to recover from our loss because we will always remember that recovering from our loss can cause us to experience more losses. Rich people can gamble whenever they want because they have a lot of money so they can use it for gambling and also for other things. They will not experience any problems except the problem of gambling addiction, which all gamblers will still experience. Rich people have more sources of income than most people, so that is what allows them to have more money than other people.
