Take heart. The fight has only begun, and Trump is and will be our President on Jan 20, 2021. Trump chose his words carefully.
Trump never said "orderly transition to... Biden". Trump posted through Dan Scavino's Twitter (Trumps's own Twitter shutdown):

“Even though I totally disagree with the outcome of the election, and the facts bear me out, nevertheless there will be an orderly transition on January 20th. I have always said we would continue our...fight to ensure that only legal votes were counted. While this represents the end of the greatest first term in presidential history, it’s only the beginning of our fight to Make America Great Again!”
