Women who are into fandom are also more likely to date man into fandom. The reason is that there are more men into fandom. So to see if it is a really relevant variant, you need to ponder by the number of men who are into sports and the number of women who practice sports.

After all, women is a gym where men are the majority, would have it easier to meet potential partners with the same interest there. While the men at that gym would have more competition.

So to see if the variant is relevant, you need to ponderate first by the proportion of men who practice sports and the proportion of women into sports. Did they practice the same sports, are all sports equally good to get dates?

The data is interesting, it is a good start.
