You have to be able to understand the math behind poker to understand this. It is a problem of permutations. In this hand, 10 people were dealt
hands, adding up to 20 cards, and then there are another 5 on the board... totaling 25 cards out of the 52 card deck.
To calculate how many ways those 25 cards can be laid out, you take 25! (aka 25*24*23*22*21*20*19*18*17*16*15*14*13*12*11*10*9*8*7*6*5*4*3*2*1)
, which comes out to 15,511,210,043,330,985,984,000,000 different ways that the board and hands can be dealt at a 10 handed table.
If there were only a 3 handed game and all 3 of them were dealt AQ, then it would be 11!(11*10*9*8*7*6*5*4*3*2*1), or 1:39,916,800 deals
