Is it unrealistic to make Unreal Engine 4 the first engine I

[wenildexis5]

I am a screenwriting major about to graduate from college soon, but I kind of have a background in computer science as well. It's been a while since I've coded anything so the blueprints are very appealing to me. I have published a mobile game with a group of other students for a class a while back using unity, but I wouldn't really say I learned too much about the engine. Would it be unrealistic for me to attempt to learn Unreal Engine 4 at this point? I'm aware that I should be starting small so I'm not even going to attempt to create an original game yet. I plan on recreating pong first.
