I think the best thing anyone told me about linear algebra was that “matrices are just the coordinate form of a linear map.” So applying the map is equivalent to multiplying it’s matrix etc.

Reality, as always, is not that simple. Matrix analysis is a huge area in itself; and matrices can also be used to represent tensors (which generally are not seen as linear maps) and some other things.
