Unfortunately, particularly in the world of sports predictions, the majority are often right. Similarly, if you look at sportsbetting platforms, they all tend to have the same or at least similar odds for their games, since they all use the same set of parameters or source for their predictions.
However, you do get some particularly skilled people that are able to spot discrepencies in the odds, where one team or player has not been given the due credit they deserve and has had the odds incorrectly stacked against them. Sadly, I'm not one of these players, as I tend to settle for small, low odds gains.
Last time I won when going against the majority was on the Wilder/Fury fight, I bet on a draw in the 11th round.
