My guess is most recommendation engines in use these days are ML/DL based. At least I can’t think of any major platform that hasn’t yet switched over, based on what I read.
I would definitely consider collaborative filtering ML, though I don’t think people normally make deep models for it. You can see on Recombee’s website that they use collaborative filtering, and use a bunch of weasel language that makes it unclear if they actually use anything else much at all
