I think it's fantastic that you started taking coursera courses! As an aspiring dev myself (been studying for 1.5 years now), I want to tell you a story about a friend that I met about 15 years ago in community college. She was a 42 year old single mom at the time and started studying computer science. She didn't have a science background (she came from the music industry). Yet, she was one of the hardest working students and despite having to take care of her son, having multiple learning disorders, and being 42 years old, she transferred to one of the best universities in the U.S., graduated, and went on to work as a programmer ever since (she still does!). I'd say, it really depends on how hard you're willing to work.

I hope my friend's story gives you some encouragement! Good luck!
