To update kernel, or not to update kernel?

I can doing some things 1000 times to working that properly. I need clarify how do that?
Fresh installation Zorin 16 is kernel 27 what I don't understand because before I installed Zorin was kernel 5.11.34 you have my photos and printscreen on forum like a proof.
I don't understand why if something working I cannot decide what I want.
New kernel can gived you unstable a computer software and peripherals device.
When I tried find kernels Zorin on websides I can find ubuntu kernels.
Why we are not get information to choice what we want install.
I know security can installing and some improve fix to better working a linux.
Here is example first ISO from servers Zorin was 5.11.0-34 from my first installation.


I don't see a low kernel 5.11.0-27
Someone can explain that?
