I want to learn how make a game, but where should I start?

I’m able to do the “artistic” part of game-development; character designing/modeling, music, environment modeling, etc.

However, I don’t have experience in programming. I don’t know what language should I learn first.
Also, many people on the internet have said that you need to be good at math and physics before learning to code… well, I’m terrible with math.
Is it true? Why do I have to learn those before programming? How far can I go without understanding math and physics? And what kind of math do I have to be knowledgeable at?
