Why not try it yourself? All you need is a Win ISO, which you can download for free.
Your BootCamp assistant will walk you through the process of making a bootable USB, including downloading the drivers that you need to complete the Win install process, including preparing a second partition on your boot drive to be the windows boot drive.
If it does not go well for you, you just run the BC assistant a second time to remove the partition that you made, taking you back to normal macOS boot, and it isn't much harder than that.
