It's way worse than that.
Even if you somehow magically have the same settings as everyone else, you're mouse movement will still be unique.
You can even render something on a canvas out of view and depending on your GPU, your graphics driver, etc the text will look different...
There is no real way to escape fingerprinting.
I have a novice coding question using the mouse tracking as an example: Is it possible to intercept and replace mouse tracking data with generic inputs? For example, could you implement an overlay that blocks mouse interactions, and instead of physically clicking on elements, send a direct packet to the application to simulate selecting those elements?
Yes, it's possible. That's the way a lot of automated web UI testing tools work. The problem with doing it during normal browser use is that your intentional actions with the real mouse wouldn't work right, or the page would start acting like you clicked on things you didn't click on.
