I assume you are asking if people make money on the Internet. Yes, people make money on the Internet. Sadly most of the money is made by people selling information on how to make money on the Internet to people who want to make money on the Internet. Most of the information sold does not work so people also end up losing money. There are more people losing money on the Internet then there are making money.
Just as in any other business, you need three things to make money on the Internet, a product to sell, someplace to sell it and someone to come to the place you are selling it that is looking for what you are selling.. Long as you have those three then you make money. On the Internet the place for people to come to is a website.
While this is way to much to go into on here let me just say that yes you can make money on the Internet and once you learn how then it is up to you to decide how much by how much effort you put in.
