I think it is still too early to say whether Neymar is addicted to playing poker or not, only being based on a single rumor. But it would not be surprising if he in fact has developed some mild addiction for card games in online casinos.
Because if his wife budget to gamble, I doubt he will get to reach a state of bankruptcy, still shows nobody is actually safe from getting hooked up by certain casinos games.
Not much to say about it... I personally find it to be distasteful, how he decidedntonplag card games like poker in the same day they were supposed to be celebrating with his daughter, it sounds kind of inappropriate to gamble when one is supposed to have family time and such.
But playing when he is celebrating his daughter's birthday is a sign of addiction. If he is just normal player, he will not do it while celebrating his daughter's birthday as he should know when and where to play poker. Not a good example of a father if it true he really did it. The question that comes to my mind is that did he play it naturally or it is just for a video content to make it viral because we all know that his name is not as popular as before when he was still in PSG or Barcelona.
There is a tiny chance he indeed made all of this on purpose, that is true, but it is unlikely, one would need to have more context on what happened, in order to have a more accurate opinion on his intentions.
You know, in the way I see it, there is a good reason why when people gather to play poker, they mostly do it in man caves or clubs where people is not expected to take children to. You have probably noticed as well, how within the popular culture of the United States, the men get together in a very comfortable place, intended to be only for adults, no kids. It is not only about the fact children could be annoying and kill the mood of the card play, but it is also about responsible parents being aware their children are not to be exposed to gambling while they are not in proper age to engage in poker (in this case).
Would you like to have some teen complaining around or some toddler crying while you try to focus on your hand while gambling against your friends? I doubt it.
