If you want to understand a bit more about Wiccan witches, it's not really that complicated. Since anyone who is truly Wiccan will practice witchcraft as part of their religion, it's safe to say that all Wiccans are "Wiccan witches". But don't try to reverse it. It doesn't work that way.
You can practice witchcraft without following the Wiccan belief system, which means you can be a witch without being a Wiccan. They are not synonymous and they do not mean the same thing. You shouldn't assume that any sort of witch is also Wiccan. You'll probably annoy them.
So what kind of person is a Wiccan witch? Well, just like trying to describe a typical Christian, there are all kinds of variations of belief and practice so that there isn't really one good definition or explanation. The Wicca for beginners page is a handy place to start to see some of the basic tenets of Wicca and what Wiccans believe in.
They likely celebrate the 8 Sabbats, follow (or at least have respect for) the Wiccan rede, and may possibly be part of a coven.
Some people do identify themselves as Wiccan even though they don't really follow the practices and beliefs of the religion. It's not just a free-for-all term for anyone who is Pagan. If you don't follow the specifics of Wicca, then you would be better off calling yourself Pagan, which is a much more general term that doesn't imply any specific belief path.
And if you are skipping the entire religion aspect of it all, then just go with a plain ole witch.
