That has been the way that AAA game development has worked the last 25 years.
Professional games are like movies, programmers are a tiny percentage of people on the set.
They are the ones caring for the lights, that all cables are working properly and special effects go off as they should.
The main role, what dictates what a game is all about, belongs to game designers, producers, artists, those aren't writing C++ code, rather using visual tools.
Naturally you can make a game old style, just like on the 8 and 16 bit days, just like there are people doing movies just with an handy-cam.

The outcome isn't not going to be same though.
