>Is there any mathematical formula that helps you to guess your chances against a similarly experienced opponent who is x% heavier or lighter than you?
No.
>Also, how does it vary in different combat sports? Does weight matter more in boxing than in MMA or BJJ or vice versa?
It matters greatly at the high levels of every sport. That's why people cut weight like lunatics.
>Is it true that +1 BJJ belt is like +10 lbs in a fight?
No.

There are a ton of things that can heavily affect the outcome of a pro fight (e.g. physique, weight, skill, fatigue, nerves, coaching, experience, injuries, referee, etc.)
Even a very talented and well prepared fighter can get KO'd out of nowhere.

The way I see it, it's about how many weapons you have in your arsenal. People tend to treat size as a single weapon when it's actually multiple. Height, weight, and physical strength are all separate factors. Having only size and nothing else already puts you at three weapons, which means your opponent hypothetically needs to surpass you in three other ways (such as speed or skill or tactics) in order to stand a chance. But in professional combat sports, pretty much everyone is fit, skilled, experienced, and coming in with a strategy, so a difference in size makes or breaks it.

There isn't enough data to get autistic about formulas. You'd need distribution of weight, makeup of tissue, all of that relative to opponents, sport specific, hand dominance, style within, injury record, and a host of other things. Sabremetrics only worked because baseball actually collected "stupid" stats over a long enough time. No fight sport has that happening on the scale and total sample size.
