Just cuz you read it on tbhe internet doesnt make it true.
No, that's not correct. The percentage does change. If you have 1,000,000,000 doors, you have a 1:1,000,000,000 chance of picking the right door. That percentage already exists, you've picked the door. It doesn't matter what happens to the other incorrect doors, the chance that you picked the right one the first time is still 1:1,000,000,000, period. It was 1 in a billion when you picked it and it's still one in a billion once the other doors are eliminated. Switching improves your odds.
