UCLA 2018 invite to Imagine Arts on April 13th

I applied as a transfer and on Friday 3/23 I received an invite to the open house on April 13th called Imagine Arts at UCLA. Has anyone received this invite in the past and then after attending received a rejection?? It says on the enrollment form, that “admitted students” get a t shirt. Am I admitted? Will they ding me suddenly for a low GPA? Doesn’t the art dept look at grades and stats to make sure this won’t happen??
