That is not what it means at all. Stars use several sources to seed the RnG, including movements of players at the table - in other words random input. No, you could not produce the same outcome every time. The players actions do not determine the cards dealt, the movements are just used as on of the sources of randomness in the deal.
And it does not matter an iota if the deck is shuffled once and dealt, or is continuously shuffled. The odds stay exactly the same.
Of course you could produce the same outcome every time in the scenario I posted. Deal the players the same hole cards and have the players play the hand the same way and the cards that hit will be the same every time.
It is 100% guaranteed that if the 9 players receive exactly the same hole cards and the hand is played, by the players, exactly the same way, the cards that are turned face-up on the table will be the same every time, that makes it as un-random as possible. The odds of that happening live are astronomical.
But the odds of that happening at Pokerstars are 1 to 1. It will happen every time if the hole cards are the same and the hand is played the same.
They should have a program that simply puts the cards in an order and leaves them that way for the duration of the hand. To decide the next card to be put face up on the clicks of the players is ridiculous and leaves them open to criticism, which they most certainly get. Mostly that's just put down as "Whinging bad player" or "You're just unlucky" but you're not unlucky, the software has shit on you because you didn't play the hand the way the software deemed you should have played it in order for you to hit your cards, or for your opponent to not hit their cards.
The software they use is made by them for them, they set the parameters and it's incredible that anyone thinks that they wouldn't have the software set to make them the most $ possible and I'm sure they know where that is.
There is nothing random about their software. Each outcome is decided by the software not by anything random. If the software decides that you calling a raise means that your opponent hit's his one-outer, how is that random?
FTR, I cash at a rate of 23% in MTT's, 27% in 90 man SNG's and 25% in 45 man SnG's and I've withdrawn $1,500 yet never deposited, so I'm not talking from a losing player's perspective.
