This question may sound stupid.
Theres a certain domain eg abc.com that does not belong to me, so that means I also won't be able to use sub.abc.com? Am I correct with this? So in order to use the abc.com domain I need to own it.

No, you dont. After all you can register xxx.com without owning .com. Technically any owner of a zone (the correct technical term) can put up a mechanism allowing third parties to register sub-zones or manage host entries.
In layman: I may register "hopppaalllaawrralla.com" and if you pay me zillion trillion dollars you can get a.hopppaalllaawrralla.com ;) If you agree. This is how all top level domains operate.
Without that, in practical terms - probably the answer is no.
