Games render graphics by sending instructions to your GPU via APIs (Application Programming Interfaces), usually DirectX 11, DirectX 12, or Vulkan.
When you play, the game is constantly drawing frames. It sends a command to the API saying, essentially, "Here is the frame, display it on the monitor."

It then overwrites the beginning of that function with a "JMP" instruction that redirects the flow of execution to the code inside medal-hook64.dll.
