Can someone go over sensitivity for me on mouse? Bit confused here

Sensitivity is 1-10. The scale on vert. and horizontal is 1:1. That’s just YOUR sense on a vertical or horizontal slant. so your sensitivity at a ratio. not like a scale of acceleration or anything like that. And zoom sense is WHAT YOUR SENSE IS zoomed in right? That’s not your sense at a scale? is it your sense TIMES zoom sense or is it just sense. for example I play around 1.4 sensitivity when I zoom in to 1.4x it’s identical right? not like scaled up 1.4x1.4. Just trying to find a middle ground here. At first I thought it was like controller where sensitivity scale is like axial offset from reach or controller. in reach you can turn all that on and off. I want like csgo where its a dead sensitivity without any offset or acceleration halo tends to impliment 5 had that thing where it would tilt if you didnt balance it but i forget what its called… anyway! am i right here?
