You should read the Rich Dad, Poor Dad series of books. You will receive a lot of information that will help you. As to your question some people buy real estate and hold it keeping it for passive income purposes. Others buy and fix up the property only to resell it and thus make a profit. These are only two models. There are a lot more details but this is not the place to do into depth.
Real estate agents / brokers / realtors make money charging commissions - in other words they get a percentage of the money when the house is sold. On the other hand it is the owners of real estate who make money when they buy a property at a low price, and then sell it at a higher price (which only works when the economy is good and prices are going up - although right now is a good time to buy with prices low, though nobody knows if they will go even lower, or when they will start to go up again).
