None of those would really be sources of statistical bias and you’re sort of assuming the poll must have been written poorly for people to be answering in certain ways or misunderstanding. All of those things you’re assuming “must be the case” are circumstantial, not statistical.
What you’ve pointed out has just been to basically say you don’t think many women play wow, when all you’ve actually got evidence for is that few women play wow with you.
Also, way more than 34% of characters are female, so that would barely make a dent in the supposed wrongness of this poll (which there is no evidence for other than your feelings)
