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.
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.
People need to learn from the existing examples of those people who ruined their lives by only trying to recover their losses which kept causing them more losses until they gambled away everything they had. They realize it sometimes but only when everything is gone, which is a very late realization.
