How much many should I make with my podcast?

So basically I got a German narrative podcast. I'm telling mainly creepypasta stories

Around 50% females and 50% males. 40k listens per month. 15% 17- 24 years old 15% 24 -30 years old And so on

I'm working with a company which put automated ads in my podcast.

I'm earning about 80 - 100 Euros per month with my podcast. I'm afraid of being scammed so I'd like to ask you guys if these numbers are realistic to you or not:)

Thank you guys
