Before you start investing, it's important to understand how the stock market works.
The stock market is an exchange, which means every time you buy a stock, it's being sold by someone else, and every time you sell a stock, it's being purchased by someone else. When you purchase a stock for a specific amount and the value of that stock appreciates in value (the share is worth more than you paid for it) that is what's known as unrealized gains. Only when you sell the stock you can lock in those gains, and the result is you making money on that stock. If it helps here's another breakdown of how the market works from Investor.gov.
