[MCU] Thor beats Surtur, Surtur beats Hela, Hela beats Thor. What is this, rock-paper-scissors?

How is that possible?

Thor wasn't fighting Surtur at his peak power when he had the weight of prophecy behind him.  Hela got blindsided by 'big as a mountain' Surtur, and Thor, and Loki, and a Valkyrie.  And even then Surtur didn't so much beat her as he blew up Asgard entirely.  
No, there's no paper-rock-scissors going on here.  Well, not outside of Korg anyway.
