I would feel much worse losing a bet with tiny odds than on something with above 1.5, but congrats to this guy for having the guts to play and win.
I think sports betting is fairer than playing in a casino, after all spending such a big bet on sports betting there is still a possibility of winning even though it all comes back to luck, I think it's clear that he seems confident in sports betting, if I were him maybe would also do the same thing, because I can't measure it from my point of view as a poor person of course betting that big is something stupid in my view, but for him having a lot of money and being a rich person will not be a problem losing money That big of course he must be gambling with money that is ready to be lost and is ready to bear the risk.
