In video poker you can't win every day. Sorry, even on positive games you will lose some days.
To a certain degree you are right. But, not in the way I suspect you are thinking. In poker the house takes enough money off the top so you are playing a with a smaller chance of success. Admittedly, skill can overcome much of that, but cards can go bad at any time.
In VP with a good positive edge it is not as important. However, you have to be aware of bankroll considerations because you can have big losing streaks even on positive games.
