No, there are many different kinds of stocks with different terms. Stocks are an asset with value, regardless of whether or not dividends are paid out. It's very commonly the case for shares to be issued with no dividends paid because profits are reinvested back into the company with the goal of increasing the share price for some future massive liquidation event (like an acquisition).

Shares also represent ownership in a company and thus their value is also in the leverage it can give potentially give you in said company.
