This is not how I see it. Carlsen lost one insanely long online bullet match on lichess.

He narrowly lost an online banter blitz match. This is not blitz, since also you have to talk while playing, which does not seem to suit Carlsen's personality.

In classical, you can often "almost lose", except that Carlsen does not "actually lose", as exemplified by his ongoing record non-loss streak.
