ELI5: what's the process that take place the moment i push a button on my controller until the movement is performed by my character?

You press button. Button closes circuit. Circuit sends electric signal to computer. Computer notices electric signal and alerts the OS. The OS takes note of what process has focus and puts a "Hey, this key has been pressed" in to the message queue of the process. The process checks message queue and sees the message. The process sets a flag that this button was pressed this frame. The code controlling your movement checks the flag when processing movement and starts moving your character.
