I've definitely seen people say it's about agency, though exactly what they mean by that and why they think that matters tends to vary. That said, I suspect your response is in line with the person I was originally responding to.
In a different context I might be more sympathetic to this specific formulation of the concept since it's not always clear how much agency the background dancers in a music video or advert have. However, on the original topic of video games, the notion of "character agency" is rather pernicious.
