Is it possible to gather entropy from weird sources from the user like mouse movements, that person's timezone, OS version and type, language preferences, screen resolution, browser fingerprint etc?
How would that be any different than atmospheric noise or die rolls? Are people's mouse movements and browser fingerprints that predictable, because last time I checked, people have a certain cadence by the way they move their mouse and the way they type, and browser fingerprinting yields very unique data which is hard to replicate and reproduce.

User mouse movements, maybe. But only while it's moving.
A person's timezone, OS version and type, language preferences, screen resolution, browser fingerprint etc... those don't change so often. So they're not really good sources of entropy.
