I may be wrong, but isn’t Worldcoin using zero knowledge proofs in their system? It would mean that nobody has access to the private data behind them - not even WC.

No, it wouldn't mean that. It would only mean that entities who verify the zero knowledge proofs do not learn anything about the data except that it satisfies the proved property.
...if you take them at their word. Oh, and ignore the bit where they will give you extra money if you agree to let them keep your biometric data on file to "improve their algorithm".
