You shouldn't play the games that don't suit you in that case and stick to what you know, which according to your own beliefs is predicting UFC fights.

It's a fight between two people, so the chances are 50/50. The bookies give both men equal chances to win, hence the 1.80 vs 2.00 odds. This fight alone won't make you look like a good predictor even if you guess the winner correctly. And if your tip is on the wrong guy, you will just tell us he was unlucky, the umpires stole it from him, he should have won, etc.

A good tipster has a history of verifiable predictions that everyone can check.
