This is a difficult question to answer without knowing more about the specific channel and what type of content it produces. Generally speaking, if a channel has 1 subscriber, they will make very little money. This is because most advertising platforms and sponsorships require a minimum number of views or subscribers before they will work with a channel. For example, YouTube requires channels to have at least 10,000 total views before they can start running ads. This means that if a channel only has 1 subscriber, they would need that subscriber to watch 10,000 videos in order for YouTube to start running ads on their videos. However, there are other ways for channels to make money even if they don't have many subscribers or views. One way is through affiliate marketing, which is where a channel promotes another company's products or services in return for commission on any sales made. Another way is through donations or tips from viewers, which can be collected using platforms like PayPal or Patreon. Finally, some channels may also sell merchandise directly to their viewers. In conclusion, how much money a channel makes with 1 subscriber depends on a variety of factors and it is hard to give an exact answer.
