What advantages do quantiles have compared to moments?

解释：
There are two potential advantages. First, quantiles are always well defined (exist) even when random variables are very heavy-tailed. Second, quantiles are less sensitive to outliers than moments.
请问一下well defined和less sensitive to outliers是一个意思么
