For mobile game development, I started with Unity. The video tutorials on their website are free and helpful to get at least a basic understanding of game development. Then I tried out Unreal. I found that the concepts I learned in Unity carried over to Unreal. I'm not a pro at either, but I did release a couple small games in Unity. I would start by at least watching the videos on Unity's website.
