Or maybe, when I see every class is 0 even Y, maybe that means all regular seats are sold, but it would still be possible to book a seat at risk of overbooking?
There is no way to know from ExpertFlyer availability if a flight is overbooked or not. Overbooking is airline and route independent. Some airlines will book only to aircraft capacity... others will overbook by 25% on some routes.
Authorized sale levels are not publicly available.
