Just like a game of Dice, when Dice has not been coming for a while, chances are that it will come, all online games are made on this principle.
Flipcoin is a 50% 50% chance, but in that situation, that limit outweighs the X person's side.
No, it's not what happens and there is no "better chance" of winning. All their bets are following a random hash. Player X just hit those unfortunate bets. What if Player Y also loses, what do you think of the situation now?
In a game like that, while relying on "luck", gamblers must also know how to manage their bankroll properly. As much as possible, they should set a maximum profit and losses per session so that it won't destroy their focus. Gamblers losses too much in a single session not because of the losing bet results but on how they managed their bankroll as they become aggressive in chasing their loss.
