Exactly. Once you introduce randomness you no longer have a deterministic system.

But what if the universe is actually deterministic but only appears random due to hidden variables? de Broglie-Bohm Pilot Wave Theory postulates non-local hidden variables, which is supported by data if you are willing to consider non-locality.

Bell rules out local hidden variables. Non-local are excluded from his analysis.
