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.
The problem is that for many people, gambling is one of the only opportunities to escape poverty. Yes, only a few people succeed, and not everywhere has a real chance of success, but it's opportunities like this that inspire people. And the rich always have a chance to become poor because of uncontrolled spending.
