Gone is the era of YOLO betting in sports. If you are that rich then you can do whatever you can with your money and just casually bet on unusual games that you have no idea of. But none of us these days are doing that anymore especially if the money that you're using to bet for is from hard earned, you will do necessary things to make sure that you've got the best probability of winning that bet. And that's why I am just using the common knowledge of what people has shared it and I think each bettor rely on the statistics that they see each game that they're interested to go on.
You are right, this is too much risk, any bettor that is taking such risk, I guess they already have a better financial stand and they probably are not much bothered if they lose or not because they staked with small amount that can be lost without chocking them. I can only make predictions that I know have a higher possibility of becoming realistic and not some game that I know too well that it's so much of a risk to place the bet on such game.
