QTo32.5751.99765.42833.573

TT is a pocket pair and QTo is an offsuit hand. One hand holds a card of the same rank as the pair, which removes a card the pair needs and makes the pair a bigger favorite.

That is a clear edge, 66.43% to 33.57%, but QTo still wins often enough that one hand proves nothing. Ties are 2.00% of the outcomes here; each tied board gives both hands half the pot.

By strength against a random hand, TT holds place 5 of 169 and QTo holds place 47.
