Clone wars? Not necessary. But Mandalorian? Yes. Basically the Boba Fett show is season 3 of Mando.
But Star Wars being self referential? Been that way since 1980.
I guess technically you could still watch this Boba Fett show as long as you have seen Return of the Jedi. All you need to know is Boba survived the Sarlacc, hung out on Tattooine for a few years and has now taken over the remnants of Jabba’s crime org.
