I don't think this article got it wrong but having it like a TL;DR of maths is a bad way to do it.
Just check the maths courses at gameinstitute.com.

IMHO, this is more a way to make people (game developers) feel mathematics intuitively.
It is somehow the same as the setosa.io approach which is all about visual explanations.
This is pretty cool.
As a grad student, I had a friend of mine who was teaching that same linear algebra course. I provided her with a lot of materials (similar to this) to help her students better understand different aspects of the material. There's a reason why the different introductory topics are taught, but often you don't really understand the topic until you get deeper into the applied material in 3rd and 4th year.
You can make someone understand maths by demonstrating cases where you would actually need maths (here, gamedev) but it doesn't refrain them from going deeper and dive into details, which would achieve their understanding of mathematical concepts.
The first step is to get the global idea (and I give you the point for setosa) but even getting imaginative wouldn't permit you to fully use these concepts if you didn't apprehended deeper points on those.
