You need to ask yourself if the friend in question is not addicted already?,  its obvious from his wordings that he only sees the positives from gambling engagement and doesn't sit back to check how much he's lost already betting daily, nor set a budget for gambling. In my own understanding, I think doing the same thing everyday, without taking a break occasionally is a very good indication of addiction.

His friend might be helpless in gambling and just trying to validate his addiction. You know that most times, gambling addicts don't see the damages they are having, they'll continue living on false hope until they are totally destroyed. That friend is living on hope that he will win one day, and the more he tries, the more the possibility of winning, which clearly  shows he isn't gambling for fun anymore, he's now overly expectant with his formula that he will be successful in gambling, which is not very rational if you seek my opinion.
