Yes, that's exactly what it means, it's been so overused that it just means the game has the coloured and the females and the alphabed soup in it.
Which sucks because it fails to describe the problem of really shit writing and design that mistakes characteristics for character.
You don't see complaints that Dudley was proto-DEI in Street Fighter because there is a lot more to his character visually and gameplay-wise than him being black. That matters, sure, part of "the joke" is that the archetypical so bri'ish innit guy is black, exactly like with Demoman in TF2 (and there's also the fact that the black skin makes lighter clothing more visually striking, which again goes very well with the archetype of the oldschool boxer fighting with his shirt on)
"DEI" is just one aspect of declining character design and writing because the characteristics it includes allow hack writers to bypass any actual effort and use these as crutches. The race or sex becomes the personnality and the story arc of the character, everything is basically a ready-made. It's one side of video game writing becoming more and more self-referrencial and trope-heavy but it's the only one that's brought up because angry gamers are morons and don't see the forest for the tree.
