How do people start day trading with little amounts and make so much?

Over the weekend, a penny stock I had 100 dollars in went up 20 percent which should be amazing. I sold and got 120 in total.

However, this obv isn't that much and 20 percent is a lottt more than what stocks usaully go up.

I'm not going to be investing millions in stocks, so how do I make large amounts of money from small starting money.

Options, forex? What will make the money go up 100%+ (ik that with high reward comes very high risk)
