The symbolic-ref command is about setting the HEAD to "point at a(nother) ref". There is no point talking about "fundamental difference" here --- the latter is plain wrong, feeding rev-parse output (which is an object name) as its second parameter.

Did you mean to ask about the difference between "git-update-ref HEAD $param" with or without --no-deref?

With --no-deref, it makes the HEAD detached even when HEAD is a symref that points at a ref, e.g. "refs/heads/master". Without that option, it updates the ref that is pointed at by the HEAD symref.
