But .txt is not the same as .rs; yet .txt is not the same as .docx, although both of these files look the same to the human eye.

A database is a file ?
Yes, of course. Even if it claims to be on a harddisk without a file system - which makes it the only file there :)
Depends on the database system. But that’s often the case.
Well, unless it is an in-memory database (which isn’t too common), it needs to be stored on disk at some point. And for storing things on disk, you use one or more files.
