Well, can a PPL fly a sim?
I flew a 747 classic sim into Kai Tak in a mile vis 3 days after my first solo. However, a bit of practice on Microsoft Flight Simulator taught me to think ahead of the aircraft. If you didn't know what to expect or were not too familiar with what is presented in front of you when you get in the sim then that might be a problem.
What I know for certain though is that it's blinding fun, give a sim a go!
