As other replies are saying, that does include the atmospheric drag. But that number wouldn't actually happen with rocket thrust. You'd never actually do that, launch a rocket from the surface of Venus - you'd first take advantage of the atmosphere to do aerodynamic flight, first carry the rocket to much higher altitude with an airplane and then ignite it from there.
