Do AI-creators not understand the process by which AI works?

I admit I have no background in artificial intelligence, computing, software designing or anything of that sort. However I use AI a lot. I am stunned by the things it can do -- sure it can sometimes make silly mistakes, but with guidance, AI can really do wonders. From writing complex codes to stories to making artworks, it's truly astounding (and alarming!) what AI can do. I admit I don't understand how all these are accomplished. as someone interested in it, I am reading up on how AI works, watching youtube videos etc, but the process seems complex.
