I built a nice tool to visualize that: https://tls.peet.ws. Its not that secret anymore though, more and more libraries are starting to allow spoofing for browser tls configs. There isnt really a cat/mouse game here - once you match the latest chrome, there is nothing to fingerprint

I do not think I understand that website. I see that JA3 always gets changed after refresh, but not sure what JA3 is. Why is it always different, and is it good or bad?

Modern browsers randomise parts of the handshake, which results in an unstable ja3. ja4 and others normalize the relevant details to make the fingerprint constant again.

How effective is it at "un-anonymizing" me? I value privacy. What do you think I can do about "any" of this?

It tends to identify your platform/browser version, with relatively low granularity. Unless you have an unusually rare OS/browser config, it won't deanon you on on its own. But it can be combined with other fingerprinting vectors.
