There are ± tolerances at every interface, so if you're off a bit on the foundation, you can balance things out in the rough frame, so by the time you get to finish framing things are pretty square/plumb/level.
But if the pre-built stuff is ±0, then there's no wiggle room in that part of the build, so the rest of it has to be that much tighter as you've not nowhere to adjust things.
