No, it doesn't. It states that the copyrighted works are the property of Cara and/or the artist who created the Works, except where otherwise noted. This specifically would cover cases where someone attempts to claim that a Work they found on Cara isn't copyrighted because a copyright notice wasn't explicitly stated, and doesn't make explicit claims over the ownership of any arbitrary Work. For it to work in the way you're claiming, the "or" cannot be present as it being there implies the existence of Works on the site which Cara does not have property rights to. Who actually possesses the property rights to any given Work is left, apparently intentionally, ambiguous.
