Zachary Castro

Zachary “Zworld” Castro is a Texas-based poker player from Flower Mound and the younger brother of fellow poker player Harvey Castro. Their competitive background extends well beyond poker: the brothers played soccer together at Marcus High School before both later moved into the live-poker scene.

Before making a name for himself at the poker table, Castro was a standout soccer player. He earned First Team All-Region honors in high school, played club soccer for the Dallas Texans, and later joined Dallas Baptist University as a 6-foot-1 forward, studying Business Entrepreneurship.

Entrepreneurship seems to have shaped Castro’s upbringing. His father, physician and healthcare entrepreneur Dr. Harvey Castro, has publicly described Zachary as interested in business ideas and passive income, even dedicating his book "The AI-Driven Entrepreneur" to him as encouragement.

Poker also runs in the family: Harvey has said he played cards with Zac early in his own poker journey, making his younger brother part of the family’s story before either became widely visible in live events. Since then, “Zworld” has appeared regularly on the live-poker scene, though there is not yet enough public evidence to call him a full-time professional.
