Elo calculates your expected win probability based on rating difference; a 400-point gap means you're *supposed* to win 90% of the time. The K-factor just decides how much a single match changes your rating. Honestly, it's never a sure thing—my Chess.com blitz games prove a 400-point lower player can still pull off a cheeky scholar's mate.
