The point is that stopping gambling is impossible IF the person does not have a great desire to stop gambling activities that have gone too far. but if a gambling addict is able to recover from his addiction and become a responsible gambler, it is not impossible that he will become a professional gambler (good or bad depending on the person's choice)
It all depends on the person still having control, so I think it's a bit useless to contact a professional if there is no desire from the addict to recover and stop gambling because it is difficult to do so, I have a friend where he has a wife who is frustrated to make her husband stop gambling even there is no other way but to invite professionals even though it still doesn't help.
This method turned out to not help him and was just a waste of time and money because his husband had no desire to stop gambling and had become a heavy addict, it all depended on himself if his husband wanted to stop gambling of course the professional could help him perfectly, but the result nothing and no, until now my friend has separated from his wife because his wife is tired of her husband's bad behavior.
I think a lot of people vastly overestimate free will. Some time ago people and society also thought that depression is just an excuse for a person who is bored with life or has nothing to do. The good thing is that now science has advanced and now people with impaired chemical metabolism in the brain can be helped with medicine.
The same is true for avid gamblers. We must admit that many of us are gamblers at heart, but often something stops us - fear of losing money, spouse\children or simply the desire to take risks is not as strong as the fear of getting some negative experience.
Unfortunately, there are always some people around us who have a higher pain threshold and there is little stopping them, even family and children.
So they except for a specialist who will help direct the gambling in the right direction, for example, in the work that you will love and from which you will enjoy, little help. Even the family is of little help in this situation, because a person who can not quit gambling and plays to the detriment of himself and his family, becomes like a drug addict and can not help himself.
