Every single game I bought up to the PS4 could be played without any downloads.
But they still couldn’t be played directly from the disk, which is part of the point of the comment you replied to. Every single game I have for PS3 requires it to be installed onto the console in order to play it.
Windows has nothing to do with it. They are talking about software applications that were made for x86. Stuff like Adobe CC, etc.
Windows runs on ARM (and has for a decade) and the apps available in the Windows app store run on ARM.
