You could be right about those examples. But the real problem is that neither of them are particularly random. The first one is easy to guess for obvious reason

You could be right about those examples. But the real problem is that neither of them are particularly random. The first one is easy to guess for obvious reasons, and the second one might be a little harder, but not much. Compared to something like the famous "correcthosebatterystaple" (https://xkcd.com/936/ https://xkcd.com/936/) they're both easy. Think of it like this: you have n^m possibilities, where n is the number of choices you have for each character, and m is the number of characters. Which number matters more?
