I wouldn't say its too late, you might have a rough start with learning and everything, but there is a lot of new technologies you can specialize in and come out on top if you invest enough time into it. Keep in mind there will be uni/college folks starting at the same time as you, regardless when you start. It's just about getting things done and get started. :)
