The clue seems to be "on your gaming PC". Many linux users still run Windows on their gaming machines due to compatibility. This would also probable be their device which has the most powerful GPU.
Although ansible can be used in local machine, but it is design for multiple remote machine. For example, if you want copy a config file to target, you must use some tools like `scp` or do some hacking. And it's much slow than shell script, and the print in stdio is ugly. (because it's design for running in 100 machines in one time.)
Ansible also had a steep learning curve, and redhat did not prepare a good beginner's manual for it. Searching the web there is only the experience of people who have used it for years, each with their own way of writing. There are no best practices for getting started easily.
