Video poker is a very volatile game, about four times as much as blackjack. In any form of gambling, short-term results mostly depend on normal mathematical randomness (what some might call luck). However, in the long run, results mostly depend on skill. If you play a game with a return of 100.76% perfectly, that does not mean that you will have a 0.76% profit every time you play. The 100.76% is an EXPECTED return. Much in the same way, if you flip a coin ten million times, the expected number of tails will be five million, but it is unlikely you will hit five million on the nose. Actual results will vary significantly from expectations, but the more you play, the closer your actual return percentage will get to the expected return.
Actually, this is somewhat of a trick question. If you are talking about a relatively short amount of play, the answer is yes they can do better than players using a proper strategy. As with all things based on randomness, it is possible that someone who plays hunches or bases their hold decisions on the flow of the game can do better than a player how strictly follows the proper strategy in the short term. In the long run, however, the player who uses the strategy will always come out ahead.
So it really pays to hunt out the good machines! But it's actually pretty easy, because the readers of a website called VPFree2 scout out the best machines and post their locations on the site.

They will plop down on any close or convenient machine and play by hunches in the hope that they will get lucky.
