That's not how it works. If the company has profits they can distribute it in many ways. Dividends is one, but not a great one because it forces you to pay taxes on it this year. Or they can buy back shares which increases the share price, which is better because then you don't have taxable income on that until you decide to sell. Or they can reinvest that money into the business to grow it, which is the ideal option, although not always possible.
