I have been receiving monthly checks from Google since 2003. My earnings are usually in the mid 4-figures.
My sites have been around for a long time and I have a great deal of traffic so that's a big reason why I earn 4 digits per month.
AdSense changed their terms and you can no longer show your earnings unless you show the finalized report. But just to be safe (they've been disabling a lot of accounts lately and I don't want to take that chance), I've blurred out my report.
I promote my sites on social media, create YouTube videos. get traffic from Google. etc. Making a lot of money with AdSense is all about numbers. The more traffic you have, the greater the earning potential.
My checks weren't always this large. I think my first month's earnings in 2003 totaled less than $20. However, as my traffic increased. so did my checks.
I cannot emphasize this enough. AdSense is NOT an overnight get-rich-quick opportunity. Even though this may look easy, please don't underestimate the amount of work I've put into my sites over the years.
You should also DIVERSIFY your income and earn money in other ways like I do with affiliate marketing, etc. Why? Because AdSense income is not stable. It fluctuates greatly from month to month.
