This to me goes to show that no one is immune from addiction. Neymar may have largeley solved his money problems but still he doesn't seem to be able to control his time spend gambling. Therefore he's seen utilizing his time very recklessly, prioritizing playing the right cards over living these once in a lifetime precious moments the best he can. And if a multimillionaire can get addicted in this way, anyone can. Consider this before spending too much of your precious time gambling. Put some limits and enjoy responsibly!
We haven't gotten direct confirmation from Neymar on this, whether he is gambling on poker games or just playing without any gambling elements in it.
But given that he has lost a lot of money in the past, it is most likely gambling and he has an addiction, but all this is not yet clear because the mainstream media always adds a lot of spice to the news they write that is interesting to read.
