At the start it's all about carrying around notes full of picking the relevant condition depending on the current permutation/state of the cube then following the step by step algorithms on which sequence of steps to perform for that condition.
Then you'll naturally realise that certain conditions happen a lot more than others and you'll start to remember the sequence of letters for each series of steps to perform.
Over time you'll forget the letters and your fingers will just know the sequence to perform when you perceive that condition, kind of like typing a password without thinking about it.
Eventually you'll be able to fit each condition and algorithm into your muscle memory and completely forget the series of letters that you used to memorise.
Now I can barely explain how to solve a rubik's cube in-person. I just do it.
You'll also notice this if you try to significantly slow down performing an algorithm, or try to solve a digital Rubik's cube where you have to click and drag to rotate sides.
