*GENERALLY*, 0 means success and non-zero an error.  But remember, every
exit code is just a programmer's choice for whatever command you're using;
there's no enforcement other than by convention.

If you're going to use an exit code from a command, take a look at the
man page and see what it's documented to mean.
