What's a possible justification for Giants not taking over the world?

An extension to another question about Why would humans be the dominant species?

In my story Giants, humans, and a bunch of other fantasy races live along side each other and i'm curious as to why wouldn't Giants (this also apply's to Yetis) be the dominant race? some basic characteristics of my Giants include:

• are 10.5ft (3.2 m) tall and weigh 619lbs (280kg)
• have bloodhound level sense of smell and greatly improved hearing
• have thick skin approaching 0.5 in (12.7 mm) at its thickest
• have Human-level intelligence
• are proportionately weaker than a human (but are still quite strong)
• have worse endurance
• are quite stocky
• have sauropod like feet
• have a gestation period of two years
• can't jump
• are surprisingly good swimmers
• have a slightly more robust stomach

Note: Magic does not exist in my world
