I've seen a lot of people state that for every scenario, Contessa wins 0/10 or 10/10. But that's not really true if we're talking in the point of view of us. Probability itself is based off quantifying uncertainty and everyone has different degrees of uncertainty based off how much knowledge they know.

Let's discuss a fight between Contessa and Batman some random peak human. Let's say Peak Human wins if he blitzes Contessa but loses if he doesn't. And let's say there's a 50/50 chance of both. For us, Contessa has a 5/10 chance of winning since we don't know if he's gonna blitz or not. But for Contessa herself, it has either a 0/10 or a 10/10 since she'll know for sure if he's gonna blitz or not.

For a non-Contessa related example about probability, let's talk about a coin flip. For us, when we see someone flip a coin, it has a 50/50 chance of being heads or tails. But for someone omniscient who knows everything from the force of the throw, the weight of the coin, the pressure in the air, etc. it's gonna be either 100% heads or 100% tails for him.

So in the end, Contessa fights only seem like 0/10 or 10/10 for herself which is not what we're looking for.
