It is a random chance to win if you go for higher odds but the probability to win your bet is more if you go for lower risk odds. I do go for higher odds myself if I see most prediction sites giving the team with higher odd chance to win base on their stats against the team with lower odd. I would bet on higher odd for single game but not in a parley because the chances of winning the bet may be reduced if you add more games to it. For example with the Chelsea vs PSG game, at a point Chelsea got about 5 odd before it started reducing to about 4 odd and that was really crazy to give a team like Chelsea such odd, which was why we got many winners from the match form betting on single. But some bettors that added games to it ended up losing. I will bet more on single higher odd.
