I checked the internet for his recorded gambling addiction and it goes back to 2018 we don't know if he is already gambling in his early years as a rapper, but we have many cases of rappers into gambling like Snoop Dog and 50 Cent they even have songs about their gambling addiction, and Drake is not the only one who posted his winning, Snoop Dog posted his one pound marijuana he won in the Canelo - Alvarez fight in his instagram account.
What happens is that it is difficult to know if such a person has been able to beat their addictions, after all many think that in order to beat an addiction completely then you need to completely stay away from it, but there are some people that can control their addictions to the point they can do so responsibly, one example of this is alcohol consumption, so while such a huge bet may seem like a sign that he is not over it, at the same time he earns so much money that if this was the only bet he made during the whole year then this is not a sign of a gambling addiction but of someone that has finally controlled his impulses.
There's no such thing about unlimited funds on which i he do continue to make big bets like this and losses then it would surely affect his financial state for long term.We dont even know if he's on profitable side or not
which we couldnt able to make out conclusions if he's doing well but in overall its none of our business on how they would be spending out their money.They have earned it and they do have the full rights
on what they would gonna do.Addiction or typical a hobby then its their choice to make.
