His perspective is essentially the same as ours would be of four-dimensional space: The space can exist, we can move through it, but we can only ever see three dimensions of it at a time. It is the same for mario and the way that makes sense to you is as a line. Even if it is a line with no inherent width, that doesn't mean that Mario cannot see it.

Yeah, that's the part I don't really understand. I'll probably have to watch some videos to get it.

You are right human (animal) eyes wouldn't be able to see a true 1D object. Then again, true 1D objects don't exist.
