Does Unity really simplify the development or rather dumbs it down to the absolute level of handholding where you don't have to think about anything?

I'm using cocos2dx with sepples and sometimes struggle with correct vector positions and getting the math right for a particular action, I manually set up sprites at correct positions and move them manually where they need to go and I guess unity does it automatically through some editor where you don't manually touch anything?

I'm actually demotivated by the fact that there are so many games on steam probably developed in unity, are the developers actually good at programming or is the unity is dumbed down so much that a brained dead drug addict can whip up a hit in a matter of weeks?
