I know Monty explained that Dust isn't magic, but I don't remember if he ever said anything about Semblance.

Sadly, his insistence on making sure everyone knew that Dust isn't magic led people to misunderstand and think he was saying there literally is no magic on Remnant, when that wasn't what he was saying.

Either way, he said that he defined magic as being able to do anything with no limitation to its use.

Dust can only do whatever its type is aligned with, and it has finite use, due to the fact that it can be depleted.

If we take Monty's definition of magic and apply it to Semblance, then Semblance isn't magic either because it can only do its own specific thing and has finite use because it uses Aura as fuel.
