Sarin is currently rated #5 on the chess.com blitz leaderboard with an absurd rating of over 3100. Online speed chess is just a different animal - ratings are different, everyone plays lots more games, and even Magnus loses fairly often. These players are all rated high enough to be competitive with Magnus at certain speed time controls, which is my point.
