If you are familiar with this American artiste you would know that he is a big time gambler or you can just say he is addicted. People are amazed he won such an amount of money in a single day but I'm not because there's a high chance that he has lost up to that amount or perhaps more than that if you calculate his losses combined. This win might actually be a way to lure people into gambling, it's very possible that the casino allowed it to happen for promotion purposes. It could be a way of advertising their casino what do you think about that? It's just a random thought, It's also very possible that he just got lucky.
Though the casinos can decide to use him in other to advertise their platforms reason been that he's a Celebrity, secondly drake is popular artist. But that's not the point here. However, everyone knows that drake is a gambler and of which we have been hearing about his gambling lifestyle but we can't possibly say that he's addicted to gambling because we can't equate him with all this random gamblers he's a Celebrity and he has different source of getting money which is why he don't care about the outcome regardless to the amount he use to stake those games.
