It's open enrollment, and even if your workplace offers insurance you should apply. If your workplace insurance is super expensive or doesn't cover things like mental health you can still qualify. When I was making poverty wages I got decent insurance with no monthly premium- even if you can't afford to go see a doctor regularly having insurance helps in an emergency.
I know so many people who don't know anything about the options they have. The government loves to take from us, the least they can do is give us healthcare.
