When you say that Turing’s universal machine can simulate any other machine, what do you mean?

The Turing machine can be used to simulate any other machine. For example, if you had a Turing machine that simulated a 3-state Turing machine, then it could simulate a 4-state Turing machine. If you had a Turing machine that simulated a 4-state Turing machine, then it could simulate a 5-state Turing machine. If you had a Turing machine that simulated a 5-state Turing machine, then it could simulate a 6-state Turing machine.
