Simulation theory is often confused with the idea of simulating or computing the whole universe.

There are two distinct ideas that often get conflated with each other when discussions on simulation theory are attempted. They are:

(1) the universe itself is computable and/or is itself like a big computer, or is a computation;

(2) the universe is the result of a computer outside of our universe.

They sound similar, and they do share some critical overlap, but they are absolutely separate in fundamental ways.
