Proves here doesn't mean mathematically or logically. Proves is an old word for the raising of dough and the baking process. The same use of the word in "proof of the pudding is in the eating."

Exception that proves the rule means something like: that one fact that is at odds with the rule but helps (im)prove it and strengthen it.

Usually wouldn't recommend wikipedia but this article is thorough af
https://en.wikipedia.org/wiki/Exception_that_proves_the_rule

There's no exception without a rule.

It's an exception so improbable that it proves that the rule is valid the vast majority of the time.

It's from legal interpretation. The exeption "no parking on Sunday" shows there is a general rule that allows parking. The way it's normally used is bullshit.
