Anyone can derive a new work from a public domain work and distribute
the result under any license they want. They could also take a public
domain work verbatim and only distribute it to people who agreed to a
contract that did not permit them to make additional copies.

This ability to take previously freely licensed works and "unfree"
them is why copyleft licensing was created:

This is entirely dependant on what you purchased and which CC licenses
you're talking about.

You should be very specific when you talk about Creative Commons
licensing because the different license types are as different as
night and day. "CC-By-NC-ND", for example, permits very few
activities, while "CC-By" is very close to public domain (it allows
people to make non-free derivatives, for example).
