Honestly, learn first how to code and while you learn and pick things up apply it to your game. Do you have a plan for how you want the game to end up?
Generally, its hard to get on a game and be a understudy of sorts. Game owners like to hire people who are known in a game and been around for some time so they can be of more help to new players etc. If my game were live and you asked day 1 can I be a staff to learn from you, I'd first want to see you login for awhile. But that's just me as I've done these games before you get many emails from players wanting things. However, coming from this platform you might get a shot. Are you on the MWG Discord channel as a starting point to get known?
But welcome to the world of coding and game development!
