HELP - 3D CNC design & running programs & PCs.

Hi there. I'm new to this & am trying to get a handle on the 'best'/better direction to go. I'm a fulltime carer & heading to 67 this year & my head works exceptionally slowly though I know how to plod through issues. Allow me to give an overview of my situation. I hope this isn't too diverse. I'm hoping you, whoever, can point me to the right articles etc.
1. I'm looking to replace the Window Mach 3 system we're running the CNC machine on.
2. Which is a 4 axis ChinaCNCzone 6040 milling machine, that’s giving me intermittent problems.
3. I want to eventually do proper animal / flower etc relief carving from my own designs. Possibly full 3D on the 4th axis.
4. I have 3 computers at present.
    a. Win 10 32 bit that runs the CNC machine.
    b. My desktop Win 10 &
    c. my laptop Win 11 system.
5. On the last 2 I've done most 2D design in FreeCAD but now am heading to Blender & am looking to  adding blenderCAM into blender which I've tried in Win 10 without success.

I'm looking to got to Lynux as it appears that most of the programs I am using are designed for that platform with Windows etc as an after thought almost.
So questions include.
1. Am I heading the right way?
2. Is Ubuntu suitable for all PCs? including 32 bit. I haver downloaded the latest already. Fun learning a new OS.
3. Can't think of another question at this point.  
Looking forwar to your helpfull directing.
CD
PS I have programmed in a previous life.
 

Thank you muchly.
So are you saying widows is better realtime processing? Isn't linuxCNC designed for lynux systems or have I misunderstood your reply?
I'll go look at Mint & check out the MX route.

Do I need a 323bit linux to work with a 32bit CNC controller??

Thank you. Can you recommend any sitte/youtube to show the full build with linuxCNC?

Windows has no realtime anything.
Windows is bad for machines.
LinuxCNC does not need controllers, it is a machine controller, so no 8 bit or 32 bit controller required.
You need:
A PC with parallel port OR a Mesa board, drives and motors.

lol  Linux good, Windows BAD....
 

instead of leaving all of them in one place ,a linux user finds ways to make it more complicated :DD!
