Not gonna speak to why they're blocking Apple Private Relay, but clearly, no, they're not implying that an IP uniquely identifies an individual. In some cases, it can identify an organization, though. One of my good friends worked for Wikipedia a while back, and he claims one of the bigger problems they had was Congressional staffers edit-warring on pages, so they blocked the IP range of US Congressional offices. They weren't trying to target a single staff. They were targeting all of them.
