I got my EMT-B first semester of college, and got an ER Tech job immediately at the one of the best hospitals in California! Most hospitals require (or at least desire) a year of ambulance experience, but since you're young they might like you a lot and see maturity in you. That's what they said about me at least, so I'm sure it'd be a somewhat similar experience for you. I also had other things like great academic performance, leadership experience, bilingual in Spanish, and a few other things, and our interview was great. You're going to work with a bunch of 25+ year old people, and they'll all consider you the baby haha (they called me Baby Boy, I was 18 when I started there). But just apply to a bunch of hospitals and it's possible. Pay's a lot better and you learn a lot 🙂 but hey, if you can't find an ER job, just get an ambulance job for a while and work your way up. One thing you get on ambulance (that you don't get in the ED as much) is assessment experience! And assessments for a doctor are one of the most important skills!
