Having done work in a variety of contexts from Game Engine development to working in Unity, what you are describing is only true for the most trivial of projects. Larger projects (especially AAA) have so much customization of the engines and pushing of their boundaries that they require just as much technical expertise as engine development for many of the required tasks.

There are advantages and disadvantages for using these engines. They soften the "getting started" part of game dev for newer people, but for complicated projects it tends to be kicking the can down the road for dealing with deeper issues.

You'd be hard pressed to squeeze good perf out Unity while fully using the HDRP and not understanding the ins and outs of the pipeline.

Agreed. I really doubt the parent comment has any idea what they're talking about.
