Very noob question but what’s the difference between Fantasy and Paranormal?

So at the risk of appearing a fool, I just found out these two have a distinction. In all my book nerd life I thought they simply mean the same thing and have been using them interchangeably. I mean, everything that’s not CR or HR that includes an element of something supernatural I basically lump them as fantasy/ paranormal. 😅

I’ve come across PNR and don’t even know what that means and now there’s even Urban fantasy sub genre. Is there like a section in this sub with all the terms and jargons?
