Yes, in general. As long as the human is accurate most of the time, the ML model will take the errors as outliers and outperform the human. The AI is generally finding trends in the data and then using those trends to predict future points. As long as the human tagging is accurate enough to get the true trend across, the AI can outperform them. It's important to understand that an AI model will perform DIFFERENTLY than a human, for better or worse, since it uses different processes. Some mistakes that a human makes, the AI would not make, but there are mistakes a human might not make that the AI will make.
