Yes, Earth-0 is the true designation of X-Men Adventures Vol 1, X-Men Adventures Vol 2, X-Men Adventures Vol 3, Adventures of The X-Men Vol 1, Spider-Man Adventures Vol 1 and Adventures of Spider-Man Vol 1 because there are too many "continuity mistakes" in those series (especially in the Spider-Man series), so it's clear the reality in those books is not Earth-92131; also, in the Spider-Man series the notes say that the events of Spider-Man Adventures Vol 1 are the "backstory" of Adventures of Spider-Man Vol 1.
