To be pedantic, they don’t create shadows, they merely indicate which texels reflect light in which direction.
Shadows (ambient diffusion? idk) are more of a bump map thing, which normal maps are sometimes conflated with and they seem to be too much of a headache for me to look into.

True, no real shadows are being cast! Normal maps are bump maps though, could you be thinking of height maps?
I thought the two were the same, talk about conflating huh?
