Yes, but at the same time you'd expect each library to be used by many applications. Say you have 100 libraries, you can make 10,000 applications just by picking 1 or 2 of those 100 libraries, applications should far outnumber libraries. Maybe applications do far outnumber libraries, but it's a fact of how people use github that everyone whose application depends on a library stars the library; as every application uses many libraries, there are many library-stars. This is a total guess, but it aligns with how I think of using stars. (though stars are separate from notifications as github documentation takes care to point out)
