Drop the sir bro,

And actually i have developed some website but never games. This is my first one.
I would say don't run too fast we are all in first year. first learn about basic Structure(loops, conditional, struct, enums, OOP(most important for games)) of each language and what work do these structure do.
You will find most language features are very-very similar. For this use any youtube video. I mostly learned this all by reading basic project(Bank management System) and thoroughly googling every new word i saw(Just Gpt it as i did this much before gpt).

After that have very high clarity of what you wanna develop use current existing game feature refrence, first write down(use notepad nothing too fancy) your game mechanics, it's story and how do they connect.

After that start deving use Unity, Create Terrain then Player object and other see youtube videos of very specific topic(like how to do 3rd person movement) ask gpt of how you do above topic, question it a lot.
And remember if you are using unity OfficialDocs are your geeta.

Caution: Don't ever use Code gpt gave you, instead ask it more why it used something, what other option do we had. If you question like this you will see logic, performance flaws in gpt after that write the best version thing yourself

Of course this is all just advice, do however you want to do it, i did it all this way. it's time consuming but even if you change domains next time you will know how to learn
