Humans have evolved to be constantly looking for patterns in their environment. Patterns allowed us to spot and evade predators, find food and identify edible plants in new surroundings. They also allow us to spot our opponent's tendancies at a poker table, and allow smart players to adapt to them. But because of how short our lives are and how little we actually get to see, we have evolved to look for and spot patterns over short periods of time, where in many cases a pattern may not actually be there. If the first 2 people going west from the settlement don't come back, we surely think going west is deadly and should be avoided, even though both those deaths might be completely random(Guy A was sick when he left and Guy B met a bandit going the other direction).
What I'm suggesting is that you're seeing a pattern that isn't actually there, as you have been evolved and trained to do all your life. A7 beating KK happens almost 30% of the time. It happening 3 times in a row happens (if I did the math right) about 3% of the time. 3% is not high odds, but FAR from impossible. So if you watch hundreds of thousands of hands of poker, and watch A7 beat KK 3 times in a row, you are seeing something rare, but something you would almost expect to see watching that many hands. And it has nothing to do with the RNG being hot, or cold, or whatever, it's just a natural occurance over that large of sample.
I know all this is easy for me to say, but trust me I've been there, and I'll be *****ing and screaming the next time it happens to be. But I play enough poker where it will happen to me, and it will suck when it does, but it's not rigged, it's not the RNG getting stuck on a certain hand, it's just that if you get it in as a 70% favorite, 3 times in 10 you will lose, and that was one of those times.
