"A dice is one in six " - that's right, but exact same principles apply. You can get 2 heads in a row, you can roll two 6's in a row, you can get the same shuffle twice in a row, it just gets proportionally less likely.
"you can believe or not believe what you want" - knowing how probability works has got nothing to do with beliefs.
"we would still only manage 4.7e28 shuffles" - some of which would be identical 🙄
