I want to know if anyone here believes you can accumulate EV? And what exactly does that mean?

Let us say a nickel VP AP gets into a one-time situation (perhaps a drawing) where he has 5 million in value/EV with a 95% chance of winning, however, he whiffs on the drawing. Did he just accumulate/bank 5 million and EV? Assuming he stays the course playing nickels I can't imagine he will come close to ever making 5 Million. Meanwhile, some other dude buys a single lottery ticket and hits for 300 mill. I think everything averages out, however, I dont think an individual can ACCUMULATE/BANK EV.
