Actually a file (size F) and a symlink (size S and 0 < S)
takes F + S while just the file takes F.
How big is a symlink?
$ touch a.txt
$ ln -s a.txt a-sy.txt
$ du -b a-sl.txt
5
5 bytes. The path to a.txt.
The advantage is one can create virtual filesystems on
a file-by-file basis. There are many use cases for that
including the one you mention ...
