The game is based on conditional probability.
I'm not going to go into scoring, 1-0, 2-0 etc but that's just an extension of this.
Two equal sides with everything equal will each have the same chance of winning. Now that doesn't mean each side takes it in turns to win, you can have an unusual run of 10 wins in a row say, but the odds are still exactly the same at the start of each game, no matter what the previous scores were
This game takes that and adds in hundreds and hundreds of new variables, each one of which has an influence on the % probability of the outcome.
But that NEVER means the score is fixed, all it does is make the stronger team more likely to win.
What people call 'troll' results are just either end of a normal 'n' shaped dice roll graph, the more you play then the more you'll see these occurring, because probability says they will, but you'll also see the stronger team consistently coming out ahead more often.
You seem to want to win every game where you are stronger (which by definition, means you lose when you are weaker) as a rule.
Think of it, that's not a very inviting game really
Bottom line is that 'troll's are infuriating annoying and just part and parcel of the algorithms that make up the game engine due to randomness,. they happen 'in-game', they are not pre set as some seem to think on here after a bad result.
