Those aren’t typically risky media. When you’re downloading games though, you’re downloading executable programs. You can do some serious damage if you execute the wrong things. You’re not executing a mkv or a pdf, you’re only reading it.
You’re half wrong and half right, .mkv files are completely safe but the same can’t be said about .pdf files, attackers can embed malicious code, such as JavaScript or hidden executables, within a PDF file.
People really underestimate the capabilities of this .pdf file format. I remember some time ago, someone managed to run doom inside a .pdf file.
There’s a difference between exploiting bugs that haven’t even been found and spreading malware through a method that’s known by pretty much everyone and is still used to spread malware today.
It’s also theoretically possible that your system is already infected by some Advanced Persistent Threats but does that happen that often, No, and have people been infected by running random pdfs they found online, Yes.
Tell that to circuit board designers. It’s horrible every time a 3d model of a circuit board is added. The component height gives no visual advantage, and it’s slow as shit on corporate computers.

Theoretically, there could also be a MKV file that exploits a bug in the video player to get execution.
Far less likely, but definitely possible.

You can embed 3d models in PDF.
You shouldn’t but you can!

My first job was extracting text from pdfs, in the end OCR was the most reasonable way. This was back in like 2010 when it was waaaaay harder.
Everyone who enjoys cosmic horror should read the PDF spec. https://pdfa.org/resource/pdf-specification-archive/
