Also, I guess that the people that wrote that did not have English as
their first language
It means that on FAT devices you indeed set the permissions for the
entire device partition. Or to be precise, you fake them.
(and it also applies to NTFS).
On non FAT devices, that is, on proper Linux devices, instead you change
the permissions of directories and permissions in the standard, ages
old, Unix way (change explicitly). You do it file by file, directory by
directory, one by one, or massively on a lot of them. But any new file
can have any other combination of ownership and permissions.
What you did with dolphin is that you change the permission of the
“parent” directory (some say the root directory, but that is confusing).
Once you have permission to write on the parent directory as a normal
user, you can, as that same user, add new files and directories, which
will belong to the user that creates them (which may or not be the one
that owns the parent directory).
Please, find a book on Unix or Linux and learn how permissions work
here. You need reading a text that explains it properly, not make
guesses at how to do things, or even ask us questions. We can not
explain it all in a post - in that case we’d write the book instead!

Documentation written by programmers is often difficult to understand by
