This is true but only to a point. I have 64GB of RAM and I have seen Photoshop overshoot that and start eating up 20gb of page file. Working with the exact same files in Affinity Photo - it uses a quarter of that.
There is a difference between “Efficiently use available memory for program functions” and “Fill all available memory with bloat and poorly coded rubbish”
If your software’s function can be replicated using only 1/4 of system memory then your software is poorly written. Which Photoshop is.
The benefit of having unused RAM is that every program you are using can remain in memory for quick multitasking access and when you go to launch a new program it can be loaded into that unused RAM without unloading any of the currently running programs. What part about that is a misunderstanding? Would the user be better off if the application in focus aggressively reserved RAM it didn’t need to slow down every other running application? Because that’s what Photoshop does
No, of course not. Why have all that RAM and not use any of it? This is a very common misunderstanding.

The part where you assumed 20GB is 100% of OP’s RAM, leaving nothing for any other programs.
