If you are going to apply next cycle, it's not wise to relay on the fact that some people got accepted with 17 AA or 17 TS. They might have high GPA, or amazing extracurricular acitivities or tons of research or volunteering hours and shadowing or they have a unique personal statement or they are urm or they might applied as disadvantaged students.
You should start preparing for a retake, so at least you can bring your DAT 1 or 2 scores up.
There is no harm in retaking, there is also no guarntee you will get anywhere even with higher GPA or DAT.
You can try your luck and apply next cycle but you'll lose a lot of money if schools didn't give you any chance.
Better safe than sorry.
