Overlap is coincidental, yes people may be doing similar kinds of things in a game. But Microsoft flight ‘simulator’ doesn’t come with a bunch of built in systems for handling loss of hydraulic pressure the way actual training systems do. The general public doesn’t want to spend time memorizing checklists for minor systems issues etc.

The other kind of simulation where people are trying to understand how systems interact is even further removed in how they are used. Running the exact same hour plus simulation repeatedly while only changing initial conditions isn’t fun, but it can be informative.
