I thought the answer was more like "all our figures are quite rough currently and a lot of work needs to be done". They mention that the current universe age fits "within the bars", for example but also mention arguments for universe being younger as well, which would again put the measurements at odds. Basically, both of these values involve a string of assumptions and while getting every single one of them to high accuracy is a remarkable achievement, the chance of some glitch in either measurement is significant.
