You own a slice of a business
A stock — also called a share or equity — represents partial ownership of a company. If a company has one billion shares and you own one hundred, you own one ten-millionth of that business.
That ownership entitles you to a proportional claim on the company's future profits, whether they are paid out as dividends or reinvested to grow the business.
What your money actually does
When you buy on an exchange, your money goes to the previous owner of the shares, not to the company. The company received money when it originally issued the shares.
You still benefit from the company's success the same way any owner does: through growth in the value of what you own and through cash the company chooses to return.
What you do not get
You do not get a guarantee, a promised return, or protection from loss. If the business fails, shareholders are last in line and can lose everything.
Educational example
Apple Inc. (AAPL)
Apple has billions of shares outstanding, so an individual holding of even a few shares is an extremely small fraction of the company. Reading Apple's own investor relations filings on EDGAR is how you would confirm, rather than assume, how many shares exist and how ownership is structured.

Why this matters
Investors who think in ownership hold through volatility. Investors who think in tickers sell during it.

Myth: Buying a stock sends money to the company.
Reality: On an exchange you buy from another investor; the company was funded when the shares were first issued.
