I doubt it's psychological (even though it's possible.) Having said that, there's a question that has 3 answers.

A friend is flipping a coin and it comes up heads 5 times in a row. What do you bet on next, heads, tails, or doesn't matter?

People who don't know much about math answer "tails". People who have learned about probability answer "it doesn't matter". Experienced gamblers answer "heads". They know that if it doesn't matter then heads is as good as tails. They know tails are not "due". But they also know that there might be some reason heads are favored somehow.

Point being, there's no reason to keep playing at that casino, unless there's some reason you haven't mentioned.

But it's probably variance and/or not playing the best strategy against the players there, who play differently than at the other places.
