Yes, it's random.

Any good player will tell you that skill is all about dealing with luck.

Seriously. Ask ANY professional poker player.

Now that random tripping is in the game, are you going to blame a loss on randomly tripping? You can't control it and it's something that will potentially make you lose. But what if you're on the opposite side and you win the match thanks to your opponent tripping? "Bad luck, that's all it was. But you still lost. Next?"
