Any upsidedown A in the set of all real characters used in academia would immediately illicit mathematical memories.

Did you mean ALL the upside up A?

Nope, it means "for any" as in no matter which one you choose it will be correct.

I usually used it as "for all", but its looks like "for any" is used too

I sit corrected. It's used as an arbitrary singular value within the proof, so for any always felt more appropriate.
