Teen Gothic

Hi there, extremely new to goth music and was wondering about the difference between darkwave and goth rock. I was googling around to try and find the right term(s) for the genre(s) I most enjoy, and found that there was a lot of overlap between listed bands and artists. Some that were mentioned under both include Christian Death, Bauhaus, The Sisters of Mercy, and Dead Can Dance. This is made even more complicated for me as Apple Music labels pretty much everything as alternative, rock, or goth rock almost interchangeably. I would just like to know if there is any meaningful difference between these terms? Thanks <3

Edit: I should also mention that Google's definitions seem a little strange, as I see bands such as Evanescence and Nine Inch Nails listed under goth rock even though I'm pretty sure they're not goth at all
