You could able to identify if the game was cut or altered and focusing only on wins.On the video given above then its real time from actions to reactions.
I dont really believe that the house do give them some special winning percentage because it was never an ethical thing to do so.It is jus on why they are
winning just because they do have that big amount of bankroll or simply speaking they have sponsored funds on which these advertisers wont really
be minding on betting $700 per roll as you can see which it is just right that they could potentially win those big hits.
I believe that they are real, the difference is that they usually gamble with a lot of money, so even the smaller returns could be a huge gain. For example 45 thousand dollars worth win could be something gigantic for me, but they may end up wagering 5k and win 9x and get that, 9x is not really that unlikely, it is quite common nearly. I am not saying that is how they do it, but having a bigger pot means that they could end up gambling for longer and longer which results with them winning a lot more money as well.
This is the way we could make a profit, we just need to make a profit based on longer terms and you will get a good return. You have 100 dollars deposited? Wager on 990x win at 0.10 cents and you will end up with one most probably, maybe you won't but there is a good chance you may end up getting it. Long story short; they have a lot of money, they try many times, eventually they hit one.
