Like I've said above, our memory is keeping bad beat moments for a long time, but we quickly forget when we're on the other side of the coin.
Any poker calculator will say that AA vs 88 is 80% to 20%
But it's true only for HU game, at a 9max table you never know true data of this equation cause you never know what cards are dealt to the rest of the players. If all aces are dealt, then it's a whole different equation. There are different mathematical systems, in one of them you're calculating things according to cards you've been dealt, but there is another mathematical system and it's dominating one.
What if 2 players go all-in without knowing their cards? Blind all-in. 2 cards vs 2 cards. What will be maths in this case? It's 50/50, or 49 vs 49 and 2% for split.
So in one mathematical system any pre-flop all-in is 50/50, In another system where you know your cards it's 80/20, after the flop numbers will change again, after the turn number will change one more time.
So how can you complain about losing with better pairs? It's usual occasion, happens to me and other players each day. You can beat it only by playing massive number of games.
YOu're a victim of so called gamblers fallacy.

If a fair coin is flipped 21 times, the probability of 21 heads is 1 in 2,097,152. The probability of flipping a head after having already flipped 20 heads in a row is
1/2
."
"Perhaps the most famous example of the gambler's fallacy occurred in a game of roulette at the Monte Carlo Casino on August 18, 1913, when the ball fell in black 26 times in a row. This was an extremely uncommon occurrence: the probability of a sequence of either red or black occurring 26 times in a row is (
18/37
)26-1 or around 1 in 66.6 million, assuming the mechanism is unbiased. Gamblers lost millions of francs betting against black, reasoning incorrectly that the streak was causing an imbalance in the randomness of the wheel, and that it had to be followed by a long streak of red"
