How much do this site earns?

Hallo, please see this https://www.semrush.com/de/info/1001sprueche.com?is_new=1

average it has 240,000 visitor from google, all from germany, this is a blog.
Can we estimate, how much can it earn? or at least how much Clicks does it have monthly?

I just checked the website. It's a quote and sayings website with a really bad and outdated design. The only ads are Adsense. He could have sold banners and a lot of other stuff.
Since the only income is adsense, I feel like it's not that much. Probably around $1000?
