Can Your Website Become a Niche Site?

[mattbop]

Hello friends, I'm not sure if this is the right place to start this topic, so if I've opened it in the wrong place, I apologize to all of you and kindly ask the Moderator friend to change its location. Like many others, I also want to create an English niche site with enthusiasm, and I've done some research on this. Could the site I shared an analysis of below be a niche site, and could even one-tenth of the CPC in the photo be possible? Thank you in advance for your valuable comments.
