Someone who is addicted to gambling to the extent that he sells assets or property just to gamble is very difficult to recover from, even doctors or psychologists will not be able to cure him.
If he can recover, he will not recover completely but rather forget about gambling and when in his daily life he still sees gambling activities he can easily return to gambling and become an addict again.
Gambling addiction must be treated as any other addiction, the first step is to realize that there is a problem, then talk about the problem and the last step is to work on a solution, but most of gambling addicts are chasing looses on the long road, and that never has a happy end.
Betting back to the topic, I don't think is the same, chasing losses is different, and the fact that someone says "I will be betting until win" is a risky move because bad streaks can be really bad and lead to a huge loss.
The feeling on winning big can never be easy to remove.
That's what makes them coming back when they hit the first loss they think they could do the same thing just like the last time they win big and keep thinking about how this time going to be their last shot just to cover this loss back to a green profit one and then they promise to quit as the final game but most of the times it is not. Nothing can beat this but a professional help might be the answer.
