You know, I was going to tackle this... but what's the point?
Well, this is a debate...
I could ask if you use the Holy Avenger or the Staff of the Magi in your game, as those require specific classes to attune to them, and I don't believe it is logical to conclude that a person could build and craft an item to reflect something that doesn't exist. But of course you are going to tell me how you've home-brewed this or make some claim about some twisting that makes it absolutely impossible to tell.
No homebrew required. Just because the magic items have game mechanics which mesh with the game mechanics of class, this doesn't mean that the creatures in game are aware of these mechanics.
I could also tell you that denying the law of averages because a wheel rolled the same type of number 17 times in a row seems to indicate you don't have a good grasp of what that means. Check the last 10,000 numbers and I'm sure it is more even than that. Check 10,000,000 and it will be even more even. That is, if it was designed to be fair and not designed to favor one side more than another.
The last 10000 numbers are more likely to be even, but that doesn't mean that they actually were even! In fact, that would be astonishingly unlikely! If your only clue to the likelihood of each is simple observation of results, it is astonishingly unlikely to lead you to the correct conclusion.
Oh, and yes, the wheels are checked to make sure they stay fair. It would not even help a casino to increase the chance of one colour at the expense of the other because the players can choose to bet on either, and we provide the means for them to track the numbers that do come up. If we made it more likely that, say, red comes up, the players can just bet on red. This would be bad for the casino; it's in their own interest to make sure the wheel is fair.
What's the point? At this crossroads it is just abundantly clear that you are bound and determined to bend over backwards to avoid any sort of title to your character beyond the backstory you thought up, and that you if hearing the term ranger or paladin used to describe a player at the table, and not having an in-game specific group that follows those names, will likely rage about it or at least be insulted by it, despite the fact that the base assumption of the game is that these are things that people can know and recognize in the world.
Assigning the lowest motives to your opponent is a common fallacy. My 'point' is simply that there is no way that the in game creature can know the mechanics of the game.
Edit: this may be coming across more angry than I intend. I am very tired at the moment, and my phrasing may be slightly off. I just don't see the point in arguing something when it has become abundantly clear we cannot agree to a baseline and you seem determined to deny any sort of baseline agreement we could come to.
I can sympathise with the lack of sleep thing, so I'm not going to get stroppy or anything. I'm not agreeing to your baseline, not out of a determination to avoid agreement, but simply because I don't agree with you.
