I am not a native speaker of English so maybe that's why. Typically anything that has lots of humor and makes the reader laugh or be amused frequently -- I think of as comedy. Is there a more nuanced distinction to what is usually called a comedy in literature / movies?

I tried to think of some other examples. Trevor Noah's biography 'Born A Crime' came to mind. I would not explicitly describe it as a comedy myself - because a 'biography' is descriptive enough as well as non-fiction by definition so any humor is mostly not made up. If it were not a biography through -- it would probably go into the comedy bucket in my mind. Maybe I am just mis applying terms here.
