I do not agree with you.

Let me paint a scenario for you. Team A and team B have met 20 times and team A has won 19 and draw only one.

You saw it when researching and you added it to your bet. When the match ended Team A lose to team B for the first time. So how do you explain that? Didn't it look like a sure bet?

Whenever I want to play sportbetting, I used to do research but I still lose my bets. But I've come across persons who don't do any of this, they'd just pick some random games, place their bet and they would win. So I think research may give you an hedge, but it's entirely based on luck.
