"package" is a generic term that can mean lots of different kinds of installer files, complex things that are used as jim describes.
A tarball on the other hand is quite specific: an archive created by the tar program, a standard UNIX utility. It's just a big dumb bundle of files, like a zip, but stores UNIX file attributes much better than zip does. Unlike zip it's designed to work linearly, so you can read the entire file, in order, extracting as you go; or create the entire file at once, beginning to end. Very handy for things that can't stop and move their heads in midstream, like tapes(or these days, sockets)... hence tape archive.
tar doesn't compress, so it's usually paired with gzip(tar -z) or bzip2(tar -j).
