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.
