Actually, you can still be getting your money in ahead and have a positive EV.
You shove AA ten times preflop and win all ten times. EV dictates you should have lost once or twice. Even though you are getting it in as an 80% favorite all ten times, you are still running above EV because you were supposed to lose 20% of the time.
Also, to the OP, beware of making all-in EV to be more than it really is. It's a common mistake to get too attached to all-in EV on the graph as the end-all, be-all of your poker luck. All-in EV does not take into account action on previous streets (maybe your betting line makes it so you typically get all-in with an insignificant amount left in your stack on the river, and your opponent makes his one-outter... to all-in ev it makes it look like you were never ahead in the hand), nor does it account for many other types of poker luck such as frequency of cooler situations such as set over set or nut over second nut type of hands.
While all-in EV CAN be useful, it is only ONE facet of poker variance which needs to be accounted for.
