For example, The Last Of Us Part II is near 100 GB, but if I record the whole game (20 hours or so) in 4K, that video will be like 200-250 GB.
Can anyone explain why?

A game very similar to a book in this aspect.
The textures have to be saved only once and then there is a lot of instructions on how to put them together. So a palm tree like a letter is saved in the files and then placed around the map, like on the pages of a book. The game only needs to remember the textures of the palm tree once and then the places where you want it.
Now recording footage is something completely different. That is like taking a full picture up to 60 times a second and storing the complete picture, without having a clue what even is on the picture. A computer makes no difference on what is on the picture, he just saves the data of color of each pixel and that is it.
When we talk about data, video is pretty much the most complicated and biggest thing you can have. One letter can be as small as 1 Byte of data up to maybe 4 Bytes. A single pixel of a picture is 3 Bytes big and you have millions of them every picture and up to 60 pictures per second.
Now you can save some data on pictures by compressing them, but a video simply is the recording of where which color was at what moment, and that takes a lot of information.
A computer game is a big smart and complex machine, but for that is has to interpret the instructions with the small graphics that were given and for that it needs a graphics card.
So it basically is the difference between somebody reading the story of a book, for which he needs a “brain” that can do the necessary calculations and the other one just knowing what every page looked like by remembering each pixel and drawing a picture of it so you can read it yourself.
