How do I get from android apps to a particular android game

I want to get from creating android apps to games. However, I want to make something like a card pack opening simulator. I will get started on how to make basic games from YouTube, but I want to know how to get from that to making this particular simulator game.

How different is it from a snake game? Where should I be heading? What keywords should I search on Google and YouTube? After making a basic snake game, where do I continue?

I don’t know if this is the right place to ask this. If not, please tell me where can I ask these types of question. Thank you so much.
