What is a coin flip in poker?

A pair against two higher cards, like QQ vs AK. The pair is a small favourite: QQ has 56.8% against AKo. Most pair-vs-overcards all-ins land between 52% and 57% for the pair.

How much of a favourite is a bigger pair?

About 4 to 1. AA vs KK is 81.9% for the aces. The smaller pair mostly needs to make a set.

What does dominated mean?

Two hands share a card, and one has the better kicker, like AK vs AQ. The dominated hand needs its kicker to come, so AK has 74.4% against AQ offsuit.

Are these odds exact?

Yes. Every possible five-card board was counted for every suit combination of both hands, so there's no simulation error.

In short

A pair against two overcards is close to a coin flip (QQ has 56.8% against AKo). A bigger pair against a smaller one is about 4 to 1 (AA has 81.9% against KK). A dominated hand, like AQ against AK, wins only about a quarter of the time.
