Yes. 50% means that they are indistinguishable. Deviation from 50% means that the channel has information about whether the subject is human or LLM. 0% is a perfect correlation (humans always correctly identify humans). 100% is a perfect inverse correlation (humans always think the machine is a human) You can identify LLMs by asking the human to pick the most human participant. Then you invert their answer. The real human is the least human like participant.
