I know a question asking if Santa exists sounds childish but parallel universe theory is a thing. So even though Santa doesn’t live at OUR north pole, does he live at the north pole in one of infinite parallel universes?

According to the quantum many-worlds interpretation, such a world would only exist if it could arise due to a random quantum fluctuation at some point in the past history of our own world—which doesn’t seem plausible in this case.
You are badly misunderstanding many worlds theory.
I’m using Wheeler’s version of the MWI, because it currently seems to be the most common one—but I think Wheeler’s version is a misunderstanding of Everett’s. So if that’s what you mean, I agree (although in that case I’d say “the Everettian interpretation” instead of “many worlds theory”).
