Probably yes for you and me, but I've observed how my parents (70+) interact with Google's search results, and for them there's no difference between an ad at the top and "real" search results.

I'm pretty sure they would consider this response as something which could be a feasible search result and would engage with it, albeit somewhat confused. They'd very likely discard it as a non-helpful response, but I'm not sure if they would know that Microsoft has injected this huge ad on purpose in order to glue them to Bing, so I don't see how they would go into full rejection-mode.

To them the internet is full of inexplicable annoyances that get in the way all the time, unless they stay in their walled garden, so they've accepted it. Even more so since they don't use an ad-blocker and therefore get bombarded with a lot of trash.
