A little simplistic there Neo . Yes, the controls operate in the same sense... but thats about it. Tell me, what happens in a 737 if you pull the control column back all the way and hold it there? Now what happens in a A3xx when you apply a rearward force to the sidestick and keep doing so? Two completely different things, of course.
The differences result in a different set of motor skills on the part of the pilot. They do, in effect, fly differently to a 737 pilot.
It's a bit like the old days, flying aircraft like the F27. you operate a Dart engine by pushing the power levers all the way forward and then using fuel trim. Try doing that with any modern engine that doesn't actually prevent you from doing so in software, and the result is a fried engine. You fly an F27 differently to a Dash 8 (for example).
