You can use adsense to make money in two ways, one, by using adsnese on your youtube videos, and two by using adsnese ads on your blog, website, or forums. The first method is completely free, you do not have to spend money to create youtube channel and do not have to spend money to monetize your channel (if you want to reach monetization faster, you might have to spend money on ads but that is not mandatory, you can actually reach monetization without spending any money). However, in order to run ads on your blogs, websites, forums, etc. you need a domain and hosting. You will have to spend money to buy domains and hosting. You also need the knowledge to set up a website. If you do not know how to set up a website, you might have to spend money hiring a developer. The only exception to this is if you use Blogspot to run your website. Blogspot is the only free platform that adsense allows. Adsense is not available on any other free platforms.
