You wanted to remove changes that you had made. Those preference files are what saves your changes to Logic's settings.
When you start Logic for the first time, there are no preference files. Logic starts up with a default starting set of preferences, and saves that config as preference files.
If you have messed things up and don't know what they are or how to change them back, then removing those preference files has the same effect as before - Logic starts up with the same initial starting point, before you customised anything - which is, I believe what you are asking for.
I would never recommend any action that wasn't "safe", I'm telling you how to do what you want. You can always save copies of those preference files if you're not sure.

Preferences are global preferences, they are not project-specific. "Project Settings" are project specific, and they will be whatever is saved in your project, but those are different things to global preferences, and won't be affected by removing your preference files.

All you would be doing is copying the app over itself, resulting in no change, so no, that is pointless. And in any case, that would leave your existing preferences intact so Logic would remain in the condition it is in now. If you've messed up Logic's content, then just delete it and redownload it from Apple - there are tool for this in Logic.
What I suggested is what I recommend you should do, unless you can be more specific as to the things you changed - and then you could just change them back again.
To be honest, you really should imo understand and know your way around both the preferences and the project settings because there are important things happening there - how to set your audio device and various Logic behaviours etc.
So, if you want to reset your global preferences, you now know the procedure, and what it does. If you've done something else you want help with, you'll need to be more specific as I have no idea what you might have done where...
Although I'm confused when you say "Logic's dmg file". Logic does not come in a DMG file, it comes from the AppStore, and the Logic Pro app will be directly placed in your Applications folder when it's downloaded. Where did this "DMG" file come from? Have you acquired Logic from somewhere other than the AppStore?
