Splash Roulette

Am I missing something, or is Splash Roulette inherently unfair? You both get a 50/50 chance to win, but you need to win 3/3 matches or you lose anyway. Maybe it gets easier in higher difficulties, since the opponent usually uses the items really ineffectively, but there are so many times already where I get absolutely fucked by rng on top of the thing about having to win all three matches
