You can simply look at the history of the team's results and see that favorites also often lose points, if they do not lose very often, but they can have draws, and if you consider that the odds on the favorite are almost always very low, then the profit from such bets can be lost much faster than it would have to be earned. So betting on favorites is normal, and this is what players most often do, but for higher odds they collect events in a pair.
That's data and only provides possibilities, right? You won't be able to guess the reality of a match going on when you believe that you will win a match, you will say that historical data is very good and it is a favorite so that it allows victory in the match, but you will not know either that the team that is considered bad, has a bad history then you gamble for its defeat at a certain time to win, conquering the favorite team in an unexpected way like luck happens on the field.
