They simply got lucky. It feels like that is the case on every site that I play on, that if you don't have a bankroll, even if you are very good "they" bust you out quickly by giving you a bad beat in order to keep money in the pockets of the largest rake earners. But ... honestly, 99.99999999% chance that it's just variance... I would like to see multiple independent organizations review the code privately in good faith to make sure nothing like this ever does happen though. But in all likelihood it's just human nature to feel this way about games of RNG at least for some people in some cases, particularly those that are getting unlucky at the time.
