The data collectors only provide anonymized data. But it's possibly for a company that collects PII to stitch together their own user profile data with the anonymous data. So, yeah, maybe. Like if you login to your car insurance website and that website is using third-party tracking to piece together a profile, they can correlate to your identity. I don't think I've actually seen this done and I'm not sure if it's entirely legal.
