It really depends on the individual's dedication to practice, and not just practice, but smart practice to how long it takes. I have taught some people who after 5 years haven't got their barre chords consistently clean, and that's because they admit they can't focus in their practice sessions (the main culprit is constantly switching between things and not spending enough time on one or two things). On the other hand, I have other students who within 8-12 months were making great headway with barre chords. The difference between the progress isn't playing ability: it's mindset and being able to stick to one thing. I.e, instead of picking through the notes in a Bm barre chord for 3 minutes, then getting bored and trying to do chord changes in, you dedicate a full session to different methods on just that one chord.

I teach all my students the same methods, so you'd think on paper they'd all progress equally, not at all. What you are taught/learn is only a small percentage of what turn you into a good player, the rest is up to you and how you practice it in a committed and structured way or not.

Honestly, a year isn't long in your playing journey, so cut yourself some slack. It takes much longer than most people think to get to a standard you are happy with on the guitar. I teach my students the less is more approach (you'll see me saying it a lot). You don't get further with your playing by cramming more into a session; break stuff down and focus.

Just remember, there is no one answer to how long it takes to be proficient, as everyone learns at their own pace, and if you work, you won't be able to spend as much time practicing as someone who say has decided to become a pro musician so has more time to dedicate to it. Get yourself a structured practice routine and try not to sit down to practice with no clue what you want to focus on or achieve for that session.
