It's never too late, if your friend really has a strong determination and commitment to get out of this problem, it's not impossible for him to recover from this problem. However, if in reality your friend is unable to realize bad behavior while gambling, this behavior can only cause continuous losses and losses. It is quite difficult for your friend to get out of this problem (gambling addiction). And I think there is no other way, apart from you continuing to try to make him aware, and that's if you really care enough about your friend's condition. And if you can, persuade him to come to a counselor so that he can get quick and appropriate treatment regarding the problems he is facing. Because if it is not handled immediately, this can become increasingly complicated and become quite difficult to find a solution to.
