What if that guy is just trolling you all? IMO, I can sense that there's the obvious on it and I don't think that it is a motivation and it's just possible that he's having fun with you all.
But let's say that it's a serious one, you can't also determine that the guy posted that is already addicted just because of that quote. He might just stomped into it and just want to share it with you so, you can think of your actions.
I don't know but for me, we need more information about the guy and his habits to say that he's already addicted not just by a single quote he shared.
This is what im thinking about trolling and having a loan just to gamble and get addictive just to lose more money this is much more worse than ruining your life future, its hard to make a joke about this gambling addiction although you're winning or losing this kind of quote needs to be on our self only not having fun around with others coz they can get ideas on how they can start gamble and end up broke in the end. you don't need more information about the guy who posted that quote we can see that see wants other to be broke period.
