In a sense, but I doubt there is the same level of tracking. Lemmy doesn’t (as far as I assume) track how long you spend on a page, what you click on, how long you stay, etc. That’s a pretty big difference compared to just what you posted or commented.
Isn’t the “user data” available for everyone to read already?

Most of them aren’t.
User data are more than post/comment history and likes. Where do you connect from (no matter whether it gives hint about your relationship status or your work and customer), which comments you didn’t write, which device you use to connect and more.
Lemmy instance I know, don’t collect much data, hence the short term of services and the lack of cookies pop up unlike big (social) media sharing their data with hundreds of " partners"
