Maybe, but a single engine Cessna without a variable pitch prop is much, much simpler than most of what will be found in commercial aviation. There's no second engine, no prop settings, flap settings are immaterial except for the most challenging landings; they probably didn't even change altitude enough to make mixture problematic. You line up a 150 right and have the settings just so, it'll land itself.
I didn't get the chance to finish my private license, but would have little concern trying to land a 150 or similar, assuming the weather were in my comfort zone. Tack on an extra engine or a variable pitch prop, and I don't have any illusions about being in over my head.
