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.
The real question should be, why would anyone think that Drake spends too much on gambling? Do y'all take the time to view this net worth(which, infact is not even that accurate)?
The boy counts in billions of dollars so, he done wagering $500k on a single ticket as it won't even feel like he's half spent.
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?
Just like you said, it's a "random" thoughts... There's no assertion over those allegations as it's been trending without any bases. I don't think stakes.com would pay a celebrity to fake his winnings to the tune of thousands of dollars just for -- FOR WHAT EXACTLY? Fame? Stakes is one of the more outstanding casinos and that got nothing to do with Drake as an artist.
