Making Looney Tunes Dash styled game. Starting advices?

I'm new on this website. I have experience in iOS apps, but never got into game development. So, I'm new in this field. I was interested to know how they make a 3D character running game style like Looney Tunes Dash by Zynga or like Despicable me: Minion rush for an iPhone. How they do it? With game engines such as Unity, Unreal or 3D modeling like combination of Maya 3d softwares for characters or...? Correct me if i am wrong. Can you give me some starting points or re-direct me somehow how and what I need to know? I know is not an easy task.

Thanks for reading my post, sorry if asking stupid things. Have a nice day everyone!
