Ubuntu and Carrier Update Process

I just though of this while rebooting into my Ubuntu Partition, I had 100+ updates (admittedly its been a while).

If Ubuntu Mobile is the same thing as the Desktop operating system, wouldn't it fall behind fast? With updates being so frequent, theres no way the Phone could stay on par with the Desktop, in the current update cycle that goes on with the carriers. I didn't see anything in the videos or hands on that would said they had a solution for this.
