Manga is used for japanese style comics while we use comics for western style drawings. if you look at the two there's differences in how we draw them. Japanese tend to focus a little more on daily life and focus on more than one type of audience and the artwork is mostly in black and white.

American (or European) comics are usually made for super heroes, though i don't read many American comics so i wouldn't really know. They do focus on the characters daily life but not as much as manga.

think of them as martial arts , there's different style like karate , jujitsu, and muay thai, but many people just tend to call it karate.

this is just what i think, i don't read alot of american comics so im not exposed to the different genres that exist in it.
