Basically this. Quarter full-pay deuces wild has a variance of 25.84 betting units per hand. If you get 500 hands/hr, in then you have a variance of 25.84*1.25*500 = $16150/hr. Standard deviation, SD, is equal to the square root of variance leading to an SD of $127/hr. Live 1/2NL has an SD similar to this if you play nitty, but unlike video poker, the opportunities for much larger win rates exist.
The high variance combined with little profit is what makes video poker hell from an advantage gaming standpoint.
