There's no way that's graduate level math. I've gone through Nando's lectures and although they're more mathematically involved than most courses, they aren't grad level math.
You might be right. The level of education is different for every individual and also people come from different country.
In America you can be a graduate in computer science without knowing calculus, and in some other country they teach calculus/probability in high school.
So the above person might have studied the chain rule and entropy in high school. So its not exactly graduate level math for everyone.

This certainly isn't true at my university in the US. As a matter of fact, I'm not sure why you named a country at all seeing as this varies by university. Anyway, I would definitely agree that on the scale of reputable international universities this is not grad-level math. A graduate school in a well-qualified university would expect students to either know this material or be able to learn it on their own. They are intro classes for the math major at my (and many other) universities.
My academic masters' program still had a couple of classes on data science and mathematical finance. So besides their research people are able to work outside academia.
