Poker Hand Ranking: Three Sevens vs. Two Pair (Kings & Fives) vs. Four Aces

From weakest to strongest:

1. Three of a Kind (Three Sevens) – beats two pair, straight, flush, etc.
2. Two Pair (Kings and Fives) – beats three of a kind? No! Standard ranking: Three of a Kind beats Two Pair.
3. Four of a Kind (Four Aces) – beats everything except Straight Flush and Royal Flush

Correction: The original answer misordered Two Pair and Three of a Kind. Three Sevens beats Kings and Fives. But Four Aces beats both.

Final ranking: Four Aces > Three Sevens > Two Pair (Kings & Fives).
