DRM is about restricting usability in practice, not in theory. Legal (or quasi-legal) documents that tell the purchaser that they can't do this or that with the game don't mean anything if there's no software- or hardware-based enforcement ensuring that you can't do this or that (without going to a lot of trouble, at least). Those integrated enforcement mechanisms (e.g. Denuvo) are the DRM (which could just as well be called DRE, since "management" is a euphemism in this case); the words in a boilerplate legalese document that few read -- and which are often partially unenforceable in a lot jurisdictions anyway -- are just that: words.

EDIT: Obviously, if any of these games required any particular store launcher to even be able to download or install the game, that would be DRM. But again, boilerplate EULA. EA clearly didn't even bother to adjust it much, if at all, for the versions of their games sold here.
