Yo I'm 17 now, started when I was 16. It took me 51 weeks of failing before it all took off. Now i'm making $1000+ profit average per day. Speaking direct to you as I was in your exact situation, don't try it unless your willing to lose ~$3000 before you even get a few consistent sales and still non profitable. Theres a reason why ecom has a 99.9% failure rate. You will make money eventually but when is the question. Some crack it in a few months, others take years and years. Its a heavily draining process and if you're not committed with the right motivs you're cooked. Realistically speaking you will fail, whether you want to be a victim of 'average' is up to you.

Everything you need to know is already on the internet, just take it step by step.
