Can a Player controller class automatically generate Input binding (project settings)?

this is how the PlayerCharacter blueprint I have looks like:

This is how it looks like under Project Settings > Input

I had to import the ini-file for the Input part so it worked.
In other words; if I delete all under Input, I cant move the character anymore. No walking around with WASD and no looking around with the mouse.

Do I understand you correctly, that the Blueprint should be able to let me move around despite nothing is set under Project Setting > Input? If yes, that’s good for me, but HOW does it work?
