I find it reliable enough. What happens in my opinion is that the RNG of poker rooms is manipulated so that it is not so random. It doesn't favor anyone specific at the table, but it tends to make the game a little easier so that weak players have a little more chance of winning. This makes sense, because if the game is 'normal' the strong player devours the weak one. However, if a weak player only loses, of course he will eventually give up on the game and stop putting money into the room. Then there will be a minority of strong players who will not put in enough money for the business to be profitable.
So, when you have an AA, open your eyes, because the probability of a 77 taking you down here is much higher than in the face-to-face game.
