Y0 (or J0 or P0) is also not an indication of an as oversold flight as the flight may have been zeroed out because of previous irregular ops that require placing pax onto the specific flight ..

The ONLY way to tell with accuracy the number of seats sold (and the bodies checked in on the day of departure) for a flight is on AA-internal sytems that non-employees would not have access to.

[I was traveling on the same flight as a non-rev that I know from my home airport .. she was able to see the ticketed pax counts - and checked in and thru - as well as the truly assigned seats - including the AWD blocked seats we see as blocked - as well as the potential miss-connects for the particular flight. We joked that by her knowing this 'detailed' information she could also see her position on the standby list and the applicable priority of others on that list.]
