If you say so but it is canon with both marvel and dc.Crossovers are not considered as valid for evidence on Rumbles.
It was in her main canon book series that lasted 50 issues and the kraven story from it was even talked about in one of spider-man's big events.Would that be the 'Squirrel Girl defeats the Marvel Universe' mini or something of that kind?
She has in canon books defeated thanos knocking him out, defeated wolverine in seconds, defeated modak, fin fang foom and deadpool three times. Defeated doom twice. All in canon books.
That's why they banned her from that jla vs avengers event. She is marvels version of the mask. She can beat anyone.
