If you are referring to "poker bots" then yes they exist. The big poker sites have invested vast sums of money to identify these bots, but you always have some that slip through the net.
On Sky Poker, my preferred site the players identified two bots by their very mechanical set way of joining and playing games. Initially Sky dismissed this, but after some significant player pressure they investigated and we never saw the said players again.
In playing the game for 6 years, this is the only instance of coming across poker bots. With regards to the rest of the players there is a significant community feeling to Sky Poker and they regularly have events in Nottingham where regulars can qualify online.
I have also made friends from the site and met several players, who unless they are a form of AI which I could not detect look human enough to me!
That aside, if you have the ability to study the game a basic grasp of maths (probability) and a solid temperament there is money to be made. It is no coincidence that one of the best female poker players in the world has a degree in astrophysics. People who have an above average IQ generally do well at the game.
