Here's my comments to you from some one who started investing at the age of eleven and spent 45+ years in the securities business.
In North America you must be 18 to open a brokerage account in your name, but a parent can open aa custodian account for you using your social security number.
And in the meantime there is nothing from preventing to learn all you can.
Before you spend $0.01 on any investment, you must know what you’re doing, why you’re doing it and how to do it and make sure you have the money to do it. Also, you must have an understanding of the rules & regulations that govern what you’re trying to do. Before you invest in any security, the first investment you should make is in yourself, and the best investment you can make is by educating yourself.
Begin your education by learning why you should invest and the importance of being able to make your own decisions or how the pro’s make theirs. Start your education by reading “Investing for Dummies” by Eric Tyson.
To continue your education, select some of the following

After you feel comfortable with what you're trying to do, visit the Web sites of some of the more popular brokerage firms. So if you feel comfortable with what you see on line and look at the cost and/or charges. When you are ready to go, just open an account with the firm using their on-line services. Please remember, the cheapest is not always the best. Even though you’re opening an account on line. you can always call the firm's "customer service" area for help
You at least have made the right decision to start investing, this is the first big step and it won’t be your last. Keep taking those steps forward and along the way never take the advice from people that are not in the market or try to tell you not to invest.
Good luck on your journey, study hard and you’ll invest well.
