ChatGPT* as a service absolutely does collect your data, though - at least on the free tier, not sure what their policy is for paying members and such.
And OpenAI is absolutely the one sifting through all that data - in an attempt to improve their LLM. I would be surprised if they were selling that data, honestly, since they of all people know how valuable it is for them to keep it to themselves.
