There are quite a large number of people who cannot cope with gambling addiction, although they realize that their favorite pastime leads to financial and psychological problems. Some people cannot get rid of gambling addiction even with the help of specialists. I have heard about such people who in a few days after outpatient treatment returned to gambling again. As I understand these people are predisposed to enjoy the risks. Apparently for them life without gambling is meaningless.
Yes true, many people don't notice it or don't want to notice it.
Realizing you have a problem is the main solution to the problem, if you have a problem and you don't want to admit it, it's hard, you can't even work on it if you think about it.
Instead, understanding helps you react and plan a way to solve it.
Realizing that you have a problem does not solve it. Take alcoholics for example, they know very well that they are alcoholics. But they are not going to quit because they like it. I think it is exactly the same with gambling addicts. If a person is already addicted and keeps losing all the money they can get their hands on, it is obviously a problem. But it does not mean that they want to stop or that they will stop even if they get the right kind of help.
