If I was the one that lost the game, I also consider it not to be my day. However, I always consider looking into the things I may doing in the wrong way, and things that need correction.
Luck is honestly a big factor in gambling . I had a bet yesterday where i just needed one point in last 2 minutes and it didnt came for over points and that i think is serious bad luck and has nothing to do with stats. But there is also bets you can win on luck and if you are on a winning streak you need to know that the luck will run out sooner or later
