How do I invest as a multi-millionaire?

So I used to work at a restaurant that gave me 9 dollars an hour and like 3 hours a week of work. I hated it due to getting low pay despite working hard. My parents were physically abuse to me and stole my earnings so I had to leave. Ever since I left I got a new job with my connections and get paid 30$ an hour. I also won the lottery and earned 2 million dollars (tax included) so ever since I won I felt like my luck has changed significantly for the better. My only problem is that I‘m new to investing and want to become a billionaire. Thats my number one passion so I become rich and prove my family wrong. All debt is paid and I live in an apartment where rent is covered by a friend who's related to the landlord. He’s doing me a huge solid. I feel like I won it big. What should I do as a 19 year old millionaire with big ambitions? I’m American, born and raised for 19 years FYI.
