Check if segment have > x or < x profiles in a Journey condition

Hi, is it be possible to check numbers of profiles in a segment in a Condition in a Journey. 

In my journey I have a read segment with 1000 profiles. If an audience (Audience A) has less than 10 profiles I need to send all profiles down this path X, if Audience A >= 500 all profiles should go down path Z.

Is this possible and what would be the a syntax for this? 

Many thanks in advance!
