Well, it sounds like he is bored from life in some way and that is why he plays poker. I would not call him addicted because he is able to control when he plays. Also he do not invest his own money, only his free coins from campaigns. Addiction means to me, when someone lost control over the decision to play and when someone set money one can not afford to lose.
It is true, he is bored and that is what he says when someone asks him why is he playing. He says he doesn't have something else to do. He's a good writer and he wanted to become a screenwriter. Some local celebrities loves his works but the finances are also a problem in our country, so he didn't get the job he dreamt of yet and thus he keeps playing.
he is addicted to gambling, when your mind only think of gambling then you are addicted, and he can stopped for a day or two but he can't quit gambling, that's mean he is addicted to gambling and I am sure during that off period he keeps on thinking about gambling and the denial of he is not addicted will make him harder to heal from addiction
This also makes sense. He stops playing for a day or two but I am not sure whether he doesn't want to or can't quit the stuff. So, summing up, maybe he is addicted but not very seriously, so it is not a problem now. In a way, we are all addicted to our hobbies, so to say.
