He has also been the image of a Poker Star, surely if you see him playing Call of Duty you wouldn't call him an addict.
On the other hand he is addicted to being unfaithful.
So what does money, fame, etc. have to do with being addicted or not, nothing, being irresponsible is not changed by money or fame.
That sounds to me like too much need for dopamine, or dopamine addiction in general. It certainly doesn't sound like acceptable behaviour but I don't know if maybe things are being taken out of context here, maybe he was playing a tournament where all you're doing is folding all the time until you get a playable hand, and it's not like he was flying a plane.
