A Set is a batch of Moments that fall under one of the following:

They are part of the same story arc, or they share a common theme (for example: they all highlight ODM gear, or they are all joke scenes, etc.)
They are part of the Base Set, in which they do not necessarily share a common theme.

The pool of potential Moments that you can get from a particular pack will generally come from the same Set.
