Meaning of „mountain jews“+assyrian

My closest genetic matches according to IllustrativeDNA are mountain jews from Azerbaijan and Georgia, followed by „Assyrians“.

This is rather vague to me. What is the genetic make-up of these groups? Assyrians barely exist these days, and I have never heard much about the history and ancestry of mountain jews. My family is certainly not jewish, and never have been as far as I know. So my results brought more questions to me than answers. What am I?
