This comment of frodo on this sam in the novel and mentioned the word magician and Warrior and tolkien did not deny that it could have been both if they are named is that there was this possibility in a hobbit and at the end says he had reason Frodo Tolkien claim not denied flatly that possibility only says that it is very strange to a hobbit Wizard or Warrior not impossible or forbidden not common only if there is a possibility has be permitted
named the same as the Warrior and magician mistrel 3 possibilities equally therefore three classes must be accepted equally
The first surprised by the personality of Sam was the bearer, and said after hearing him sing the song about Trolls , opposite the statues of Tom , Berto and Guille Estrujónez : "(...) I'm learning a lot about Sam Gamgee in this trip. was first a conspirator and is now a minstrel. It will end by being a magician or a warrior ...! ... "and he was right.
This doesn't actually say what you think it does... the full quote goes like this as Tolkien wrote it:
Sam muttered something inaudible. 'It's out of his own head, of course,' said Frodo. 'I am learning a lot about Sam Gamgee on this journey. First he was a conspirator, now he's a jester. He'll end up by becoming a wizard – or a warrior!'
'I hope not,' said Sam. 'I don't want to be neither!'
- FOTR, 'Flight to the Ford'
So it's not 'minstrel' and 'magician', it's 'jester' and 'wizard' - and Frodo obviously can't be right about the wizard part, and in any case is plainly not being serious, it's just banter. This might, however, be an instance of foresight because he's right about Sam becoming a warrior, as we find out later. But we know hobbits can be warriors, and they can do that in the game already. But don't try to use that quote as another excuse for hobbits doing magic.
