Yeah, that's true! The reason I looked into this in the first place because the basics of movement in chess are fairly straightforward until you take a look at some of the weirder edge cases. Knights seem like the simplest out of the "weird" cases :)
I think the easiest way to conceptualize the knight's movement is that the knight moves to the nearest squares that no other piece could move to. In a sense the knight's moves are the complement of the other pieces' moves.
