The surfaces you're seeing in the pictures are almost all the "bottom" surface that was printed directly on the build plate. It basically just picks up the texture of the build plate and is otherwise smooth. That's actually a fairly bumpy build plate they printed it on (which lots of people like for aesthetic reasons).
That said modern 3D printers are good at producing pretty nice parts these days, especially if you print with small layer heights. You might be underestimating the possible quality of 3d printed objects.
