Why wasn't my app published on google play?

Question

Google Play

I can't figure out why my app was rejected on google play? My application is a poker dictionary, in which there is one advertising banner related to poker, in the settings I specified the age limit 18+. As I understand it, it was rejected for inappropriate advertising in the application. The advertising banner was from pokermatch. Here's what they sent in the email: Hi Developers at Buratino Apps, After a recent review, we've found an issue with your app, Poker Dictionary (com.buratinoapps.pokerdictionary). See below for more information about your app's status and how to correct the issue.
Publishing
status: Rejected
Your app has been rejected and wasn't published due to a policy violation. If you submitted an update, the previous version of your app is still available on Google Play.
Reasons of violation
Issue: Violation of Inappropriate Ads policy
The ads shown within your app must be appropriate for the intended audience of your app, even if the content by itself is otherwise compliant with our policies. For example, ads that show mature content or services cannot be served in apps that have a content rating for younger audiences.
Next steps: Submit your app for another review
1. Read through the Inappropriate Ads policy, Content Ratings page, and Help Center article for additional details.
2. Take appropriate steps to ensure that your ads services and ad content filtering are set appropriately for the content rating of your app.
You may need to check with your ad service provider to make sure the advertising campaigns you selected will only show content consistent with your app's intended audience.
If you use AdMob, please refer to the AdMob Help Center for more details on ad content filtering.
3. Sign in to your Play Console and submit the update to your app.
If you've reviewed the policy and feel our decision may have been in error, please reach out to our policy support team. We'll get back to you within 2 business days. Please help us improve the developer experience by completing this two question survey.

naked aunts in general can be from 18 in all states, but there are nuances with others (for example, alcohol from 21 is also in all)
