No. Wicca is just one branch of witchcraft. It is classified as a religion.
However, witchcraft is not often about the worship of deities. I'm a witch, and I'm not religious. I have certain beliefs, but they are ones that I developed myself and nothing to do with organized religion.
What you have to understand is that you get to make the rules. No-one can say you have to do this or that. It's your life.
What I will advise, though, is that if you are very young, you will do well to research and read as much as you can find. Only by exploring by yourself, will you find out what is right for you?
