Beyond what we know about the show from watching it ourselves, the staff behind the Disney+ series have said as such that it isn’t about Boba Fett. 

“Boba Fett is a clone, according to Attack of the Clones, and by asking [creator George Lucas], he would say Boba Fett is not Mandalorian, not born on Mandalore,” explained executive producer Dave Filoni during a conversation with Entertainment Weekly. “He’s more of a person indoctrinated into it, into the way of life, and gets a hold of the armor.”
