I agree with your opinion, that a gambler will not become an addict if he is aware of all the risks when playing, if he plays too much, puts money in the hope of winning, of course that is impossible, on the contrary he will lose. all the money will be lost. And that will cause problems in his family and the problem in him is that he will regret having done that without thinking about other people.
In the case of gambling addicts they are harmful not only to the family but also to the society. At the beginning greed works in them to get more and when the rush reaches the point of desperation when everything is lost, taking a break from gambling will seem like the last thing you want, but it is necessary. Leaving gamblers after losing their large amount of money will give you the space and time to evaluate why it happened and how to prevent it from happening again. But a responsible gambler does not get greedy after earning a profit, they know the right rules of gambling so they are less likely to suffer.
Very few people normally have the mind to leave after they have suffered loss,the only thing that rings in the mind of a loser is to try again,but it's always very unfortunate that the winning won't still come,which is always really frustrating.
Gambling addiction is one thing that has destroyed so many lifes,but addicts find it very difficult to stop it because the spirit that backs gambling is stronger than one can even imagine or think of.It just what one needs to do with caution to avoid being in a serious mess of not being able to do without it,which has had so many person lose their lifes as a result of depression.
