You are safe for a particular aadsas batch when your gpa is verified and you submitted the application and paid the fee.
However, whether your application is "complete" and worth reviewing is totally dependent on the school. Most of the time, schools will only review your app after secondary fee, dat scores, primary, and lors are complete.
Because most schools won't consider your package until you pay your secondary fee and submit the supplemental, one could conclude it to be "rolling".
The sooner you get your secondary fee and supplemental turned in the faster your package would be "complete" and thus reviewed by a particular school.
