Question Gamimg mouse for FPS

[Pupq1]

Hi I'm looking for a new gaming mouse. I mostly play CSGO and Fortnite with a Qilive Q.8849
So I have some questions regarding mouse accuracy
1. Does more dpi mean a mouse is more accurate, even if you use max dpi
E.g. from my understanding, a 12k dpi mouse set to 800 dpi will perform better than a 8.2k dpi mouse set to 800 dpi aswell. Is that right?

2. How should I balance my mouse dpi and in-game sensitivity for the best results? For example in Fortnite I use 800 dpi with 0.07 in-game sensitivity and man my aim is f*cking garbage xD especially when tracking, my cursor doesn't move smolthly. So should I set the dpi to a few thousands dpi and lower the in-game to match it?

And also, is the ROG Gladius II Origin a good deal for $65?

a two decade FPS veteran here, Doom (the original) through Ring of Elysium, (check it out free on steam) and through it all I have had the same mouse. it used to be white and they added a couple buttons, but the same great device.
Logitech mouseman marble. I know its technically a trackball but every time I loan out my spare, they buy one for themselves. more accurate to aim and be able to fire without the mouse moving, you can click and the mouse will not move. move your fingers not your hand.
