To be fair, there is no real distinction between the observable universe and the whole universe. Saying there is a difference seems to say that there is a universe outside the universe.

No. That isn't what that means. If you can't see beyond the horizon, it doesn't mean a new world starts at the horizon, the world just continues. If you can't see stars beyond this galaxy, it doesn't mean another galaxy would have to start where we can no longer see. The observable universe is just the region of space that light had had enough time to reach us in, it doesn't mean that is the edge of reality.
