I believe every gambler can attest to the little odds they have lost before. Most times in my area, I see some guys criticizing the club they bet on because they had small odds and yet busted their bets. 

Every gambler has their own strategy of betting, so no regrets for that guy who lost $1.4 million; he was just so unlucky and can try again next time, lol 🤣😂

I have learned lots of lessons in gambling, and even if I were in his shoes, I would not have just wagered $1.4 million on one game, but I noticed that some Rushian gambling sites do not allow me to split my options when gambling on a particular game; for instance, if I bet on Chelsea to win, the site will not allow me to bet on the same game with a different option, like Chelsea to lose. So what I do is use a common betting site that allows me to diversify my options in one game. What I am saying in essence is that even if I am presented with a small odd and have to go with different option, I can split it into three options and also split my fund accordingly. If one option busts, I might still be lucky in the other. 

But how can he take such a risk by wagering $1.4 million just for a net profit of $11,200, which is 8% of the total wage if he had won? OP, I agree with the lessons you stated out of the story.
