Count esports too, not just sports. I think esports have the same thing. You can easily predict who should win if you know enough about them, easier than playing in a casino. Of course, nothing is 100% sure, but the chance is higher, especially when one team is super strong and keeps winning all the rounds in a year. 
It makes me confident to keep betting on them for all the matches till the end.

We can determine the chances of winning if we are experienced and know the match situation of the two teams or teams currently competing.
Therefore, to minimize risk, we only need to bet on matches where we really know the teams competing. so we won't easily lose bets.
But of course I also agree that it doesn't guarantee that we will actually win the bet, because anything can happen. Luck and other factors will also greatly influence the outcome of the match at the end. There is no 100% guarantee of winning in gambling, we can only analyze and predict how the match will go looking at their performance in all the games they play, from there we conclude and make a decision about which team we will trust and for the final result there is no who knows for sure about it.
We only analyze and cannot be sure whether we will win or not.
