Found this wikipedia pages of the world’s best-selling fiction authors (all time). Kind of fun to look at. Most wrote in English though its an international list (we’ve won the language lottery because we can all write in English). Most of these folks wrote at least a few dozen books, with many well over a hundred. Lots of great story-tellers on this list. If you like short stories I recommend picking up any Louis L’Amour collections if you never have. They can be found everywhere. Most of the collections are a mix of genres: South Seas adventure, westerns, crime stories, sort of like uncovering a bunch of new Humphrey Bogart movies: really satisfying reads.
