Well, then. That settles that question.
It also makes it more clear about the procedural generation. They said everyone starts out in a new, undiscovered system of their own on the farthest edge of the universe and the basic goal is to get to the center of the galaxy where, apparently, an Antagonist of some sort is waiting to be "dealt with" in some way.
The procedural generation most likely occurs at the EDGES of this universe and just builds outward as new people create accounts to join the game. When a new player joins the game for the first time, it sounds like the server creates an attachment solar-system for them to start out in. They then can explore their own new system, or neighboring systems and then eventually work their way into the center of the known universe.
So, the interior of the universe is most likely pre-generated ahead of time and everything new get's tacked on to the current outer-edges of the universe.
At least, that's what it sounds like to me??
The game has an algorithm for generating planets and the like, the algorithm is the same for everyone so the results are always the same. They aren't hand crafting anything, but it's not randomized in the sense that something like Diablo was.
