Looks like someone read Theory of Poker, or at least the first chapter...
The nature of poker is that the better a player, the more often he will put
his money in when he is ahead. Conversely, the weaker the player, the more
often he will put his money in whilst behind. It is therefore natural
that the good player will not need to outdrawn his opponent very often,
whilst the weaker player has to do it with much greater frequency. Of
course, the good player makes more money in the long run, but the weaker
player will still win pots from him. It's a fact that in the long run, the
good player will outdraw opponents fewer times per hour than he will be
outdrawn on himself.
This concept is right from there, worded slightly differently.
Honestly dude, this hand example is not out of the ordinary. If you think the site is rigged, don't play there.
