Things I would need to learn [closed]

Hello everyone and thanks in advance for helping me out. I just graduated from a video game conception school and I want to get into UX for video game or mobile app. The issue is: I don't know where to start. I am already very comfortable with Adobe products but I don't know anything about coding. So I'm not sure about the next step to take.

Should I learn HTML & CSS? Should I learn Java or any programming language? Do you recommend this course? Udemy mobile app design

My goal is to develop a skill in UX that is strong enough so I can partner up with a programmer and create app or games.

Thanks.
