Hi! It sounds like you are not a systems engineer! Let me help:
When installing Windows Server, there is a "core" experience and a "desktop" experience option. The former is now the default, but nearly all enterprise software not made by Microsoft (and some that is made by Microsoft) require the latter. Including many tools which expect to run on domain controllers! Some software says it requires the GUI but you can trick into running without if you're clever and adventurous.
No GUI is definitely the future and the way to go when you can, but even the most aggressive environments with avoiding the GUI end up with a mix of both.
Speaking of a gaming PC, Edge on Windows Server is so badly implemented, I have a server that is CPU pegged from a botched install of "Edge Game Mode" a feature for letting you use Edge in an overlay while gaming. I don't think it should have been auto installed on Windows Server, but I guess those engineers at Microsoft making triple my salary know better!
