The inverse gambler's fallacy is when someone thinks that because something has happened many times in a row, it won't happen again. It's like flipping a fair coin. You flip the coin twice and it lands on heads. Your friend might think that because it's landed on heads two times in a row, it's now more likely to land on tails. But this isn't true. Even though it landed on heads two times, it's still just as likely to land on heads as it is to land on tails. So the inverse gambler's fallacy would be thinking that because it has landed on heads two times in a row, it won't land on heads again.
