Google Play requirements for gambling are not that simple and very limited to a few countries. We are trying to submit the game to Google Play and AppStore.
Google has term and service for games developer
https://developers.google.com/games/services/terms you have to read carefully. If rejected you can submit your games to another vendor like
amazon mobile aplication, Aptoide, ApkMirror, ApkPure, etc. Seems you need mass marketing when launching mobile app besides play store.
