FALSE! Creativity can be learned.We teach our brains to be more creative. Example, Edward de bono uses the six thinking hats to teach you to be creative.

I'm really sure that lots of famous artists developed the skill to be creative. I don't think most artist's ancestors were famous artists too. Someone who was once very poor in art is now excelling in art! Example, my mum?(i'm just randomly picking someone) She used to tell me that she was once getting c's and d's for art when in primary school, but now , whenever i have difficulty in drawing, she would always support me with all sort of ideas.
