Able to contribute to ML is already better than many of us, so congrats and don't downplay it.
As a general rule of thumb, I would say just be yourself, be good to others in general and there's no rush for it (some people would choose to like or not like you, and it's totally fine). It takes time (~10+ year) to be mature.
When I was your age, I have no clue too other than just finishing my first public exam. I happened to work for a community center to promote the usage of Internet as a summer job. That job transforms me to be more confident in front of people as I need to face people in different walk of lives. It's a good starting point as I can use my computer skill as a stepping stone.
