My AdSense revenue is very low

I have an online tool website. Below I'm sharing the screenshot of my AdSense report, where you can see the monthly revenues of 2022.

As you can see in my reports, my website received a total of 43,350,761 page views in 2022. When we divide this by 12, it makes 3,612,563 page views per month.

In the calculation I made by selecting the relevant region, category and monthly page views on https://adsense.google.com/start/#calculator , Google tells me that I will earn an estimated $457,550 annually. When we divide this by 12, it makes $38,129 per month.

But as you can see in my reports, I earned $10,373 in total in 2022. On a monthly basis, I earned between $600 - $1,200. That's exactly 2% of what the Google AdSense Revenue Calculator gives! As you can see there is a huge difference!

Google AdSense Revenue Calculator gives an estimated value, it does not reflect reality. It is natural to have a difference with real AdSense revenues. But the difference being this large indicates a problem with my site.

Why is my website revenue so low than it should be?
