Sounds more like gambling than science; you're making a one in six bet that you can dupe me. More seriously, I would not accept your claim with evidence as weak as that. Roll the dice a few more times and then I'll credit your claim. Rolling the dice only once when you could just as easily roll them a dozen times is junk science.

Incidentally, this trick is something magicians sometimes do. Sometimes when a trick has gone wrong they'll make a wild guess. If they're right, the audience is impressed. If they're wrong, they'll brush it aside with some joke and the audience won't notice/mind much. This works for things card guessing tricks and puedo-psychic/cold reading stuff.
