I don't believe that to be the case, even a really good FF wheel comes no where close to the feedback you get from the g-forces you can feel and the feedback through the wheel about what the tyres/suspension/engine are doing when driving a real car, and it's how you judge and react to that feedback that makes a skilled driver.
That being said, you will learn simple things that you may not learn from average speed driving on public roads, like if you go into a corner too quickly the car will likely under-steer, a RWD car will tend to overseer if you're too early on the power on the exit of a corner and how locking your breaks will reduce slowing force, but how to handle those characteristics in a real car cannot be learned playing a game, I learned how to drive properly on empty country roads in a relatively fast and good handling road car.
