How are cheats for games created?

Question

reverse engineering

Hello.
I am a beginner programmer, I watched video tutorials on c++ and c# and so on. I want to be a coder, well, create third-party software and so on. For example, I watched tutorials where they create Cheats for the CS:GO game, and there I don’t understand one thing at all, for example, there are PlayerBox lines and so on, but when I studied the language, I never saw such lines, so what is it? each game is different, how do you know? How to search for them at all? Is there a DirectX connection at all there? It’s just that I don’t catch up with all this, don’t scold me if I write something wrong, as I said earlier, I’m a beginner;) Thanks for the answer.

Imagine that you have written a game in which a man runs through a maze and collects treasures.
If he falls from a height x, then he dies and 1 life is taken from him, and the level starts from the beginning.
To take a life, it's just a number with the number of lives stored somewhere, and somewhere there is a command that takes away one there.
The task of the cheater is to find this team and remove it. After that, lives are endless.
Or you can find the place in memory where lives are stored and put 100 there.
Or you can find the place where it is considered from what height he dies, and put it much higher there so that he does not die.
Or replace the command -1 with +1, and the number of lives will increase.
In general, cheating does not need to learn special magic, you just need to learn how to program, and understand how programs work. Then you can try to correct them.
Well, games are written in different languages.
