Right - really "no license".

Public Domain means anyone is free to take it and use it however they
want - including pulling into another app and re-licensing it.

One of the ways people can contribute to GNU projects is to explicitly
assign copyright of code to the FSF.  The other way is to disclaim
your work into the public domain, at which point the GNU project
maintainer may pick it up and include it in a GNU-licensed
application.  Changes to the code will carry the FSF copyright, and
the whole will carry the GNU license.  (see
parted/libparted/labels/gpt.c for such an example if you're curious).
