PragerU is absolutely garbage. Their "production value" is full of fun charts like this: https://pbs.twimg.com/media/DyNY9z-WwAAY5xL.jpg:large
The chart is from the video "Why is Modern Art so Bad?" published September 1, 2014 with artist Robert Florczak and is available here (5min 49sec): https://www.youtube.com/watch?v=lNI07egoefc
The chart you've linked is presented at 1min53sec (https://youtu.be/lNI07egoefc?t=113) and it's not a key part of his views or arguments. It's shorter than a talk-show skit, even if you don't agree to what he has to say, I suggest watching it.
They say a lot of things that "feel true" if you're disaffected, surround it with pseudo-intellectualism, and then tell you who you're now better than.
I find their clips pretty useful for honest summaries of what conservative positions are on an issue and why.
