The mean age of swimmers for all of these teams is 10 what does a large MAD tell you?

MAD which is know as mean absolute deviation gives us the mean of the absolute deviation of each of the data points from the mean of the data set.

The large mean tells us that there is a greater variability in the data i.e. the data is spread out which leads to the larger deviation of  the data points from the mean of the data.

Here the mean age of swimmers for all the teams is 10

Hence, the larger MAD tells that there are swimmers whose age are much more than 10 and hence the deviation from mean will be more and hence leads to larger MAD.
