It is very likely that something unlikely will happen. There are many unlikely possibilities, and many things happen, so at the meta-level you should not be surprised that you are frequently surprised. This is a probability refresher for players and fans of weighted random number generators with attached narratives, although it applies generally in life. In a world with seven billion people, one-in-a-million events happen all the time.
Many people see something suspicious, meaningful, portentous, etc. in unlikely occurrences because they are over-specifying the event and ignoring the population of possible events. There probably is no conspiracy against you, nor did they change the accuracy code in your game.
I call the event “over-specified” because you are pondering how unlikely the particular event is rather than the likelihood of a member of that class of events. What is the chance that the car in front of you will have your spouse’s birthday in its license plate number? Pretty small. What is the chance that at least one car in front of you today will have a number that is somehow interesting in its license plate number? That is a long list of possible unlikely events, and while it might be surprising to notice a particular one, we have a lot of winning numbers in that lottery. Remember that this particular unlikely event is not the only one that you would have found surprising if it came up.
The “population of events” is how many chances there are for something unlikely to happen. We forget how very, very many of these there are. My standard example is having streaks of misses in a game. If you have a 90% chance to hit, the chance of missing 5 times in a row is 1 in 100,000. That is pretty unlikely. But if 2 million people are playing WoW every day, and each of them attacks once every five seconds for an hour per day, several people should have that 5-miss streak every minute. If even a small percentage complain about it, it will sound like a constant cacophony about horribly buggy code in the game’s to-hit rolls, but it is just a perfectly normal result of a random process with a lot of trials. Flipping back a paragraph, the more you drive, the more chances you have to see unlikely license plates, and then add in everyone else who might tell you if s/he saw one. Given enough rolls of the dice, incredibly unlikely chances become absolutely certain.
For your linking convenience the next time someone indicts the developers for perfectly predictable streaks in random number generators without suggesting why this streak is meaningful, or for instances of “it’s a sign” more generally. Try not to stomp on anyone who finds simple joy in noticing license plate numbers, so long as s/he is not making major life decisions based on them.
