The other commenter is correct! The tagset is just what's available to be requested/offered and there is no guarantee (in fact, it is highly unlikely) that all nominated fandoms will be requested.

As the other comment suggests, do check out the unofficial app for an easy look at what requests people have made specifically. https://autoao3app.firebaseapp.com/#/smut4smut2024

Note that until sign-ups close, it's possible for people to delete or edit their requests so I would double-check after sign-ups have closed to ensure the request is still there and doesn't have any new added details.
