I wouldn't fixate on the Google part too much. It's pretty clear he is using it as a common point of reference for 14 and 15 year olds. "You guys know about Google?, the giant company with the web site? Okay well let me tell you how companies like that are built."
Building a successful company depends on many things. The point made here is that you are unlikely to be expert enough, and motivated enough to build a successful business in an area you are not interested in, and haven't played around in. So to increase the amount of domains that you could create a business in from 0 to a small positive integer you should build things that interest you.
Of course if you have money, or know how to persuade people who have money, you can be something of an idiot and still develop a successful business. Usually you are not really developing the business in this case, more attaching yourself to a business that smart people are running for you.
In a pool of high school freshmen, most probably have a better chance of success following the first path, than the second.
