Why Sean could get the result from YouTube Videos network but I could not?

I chose only YouTube Videos network over only India for checking whether I could get subscribe or not. But there was no click to the link. However,i could get subscriber from 4-6 views over India when I chose search only network. So,I decided that i should choose only search network and also chose the USA as a country. But i could get very very low impression and even no any view to video when i chose only search network.
Sean chooses both of two network over the USA in video lessons.
Why he could get the result from YouTube Videos network but I could not?
