Am I right(dividend question)?

For example there are company with capitalisation of 1000$.Price of each stock is 10$, I have 10 stocks so I own 10% of the company(100$).

So am I right that all dividends are not paid at once and how much will be paid depends on dividend yield.So if dividend yield of this company is 20% and dividends are paid each year, then I will receive 20$ per year???
