I know very little about Wicca so I'm going to let someone else who believes and practices in it to answer that part of your post.

As for agnosticism, it's more of a philosophy as opposed to a religion. There are different types of agnosticism, one of which is agnostic atheism and it states there MAY be no god, thereby allowing, although doubtful, for a god to exist. Alternatively, there's pragmatic agnosticism, which does not concern itself with answering whether a god may or may not exist. Instead, it suggests if a god exists, it doesn't give a crap about people so there's no use in believing in one since nothing will come out of it. There are other types but I think it's best for you to look them up online instead of adhering to whatever label some anonymous person on the Internet posts.
