It's always possible that if so many candidates get this wrong, especially senior ones that your understanding might be incomplete, or possible not understanding clearly. I often find that people get these pet questions and think they understand them when they don't really. I'm not even a data scientist or statistician and could tell you what a p-value is. I find it hard to believe experienced candidates can't.
