Yes, but then again, completely no. I mean, a procedural generation algorithm for a game world is an artwork tuned to produce results the artist likes, usually with care to allow some cases and exclude others and meet a particular vision. It's not very different from a pre-made world, except using the RNG as one of its building blocks.
