Proto, it's pretty much common knowledge to anyone in the star wars nerd community that boba fett isn't dead. He shows up in a whole bunch of canon after return of the jedi and I think some book explains how he got out of the pit.
I read that when I was like 14, so it's kinda old news
Edit: Also, it was a good read. There was a site that I came across a couple years ago that had really big lists of that kind of thing for every star wars movie and it was really funny. Now I'm gonna try to find it
