My group was smallish when I drug myself back into AA in '82. The people there who had a year have either died sober or are still ahead of me 28 years later. None have drank again. 100% of them have stayed 100% sober so far. No guarantees, but they're looking pretty good.
We've always had a ton of newcomers blow in and out each year, but about one a year actually does the steps and because of that, sticks like the rest of us.
Hopefully you'd like to stick instead of being part of the chaff that constantly blows in and out of AA whenever the door opens.
