Her parents are Marc Rousso and Cynthia Bradley of Hobe Sound. Rousso began talking and reading at early ages says her mother, Cynthia Ferrara. Born in New York, she moved with her family to France at age 3. She lived in Paris, in her father's homeland until she was 10, when she moved briefly to Upstate New York. After her parents divorced in 1992, her mother moved Vanessa to Florida near her maternal grandparents. Rousso attended Wellington Landings Middle School. The oldest of three athletic girls, Rousso was active on the high school swimming, lacrosse and debate teams. She also played softball and basketball for fun. In debate, Rousso excelled in national debate tournaments in policy debate. Her mother is a guidance counselor at Jupiter Community High School. In 2001, Rousso graduated as valedictorian of her high school in Wellington, Florida.

She was also active as a violinist, varsity swimmer, and volunteer for Mothers Against Drunk Drivers. Rousso has two younger sisters: Tiffany a psychology master's student at Florida Atlantic University and Leticia, a pre-med student at University of Florida.

In college, she was on the Dean's list. After studying some game theory, she became proficient with the Rubik's Cube and then chess. However, because she considers both to be fairly objective static games, she began to prefer poker, which incorporated human psychology that allows for inferior hands to win. She graduated early from Duke University after two and a half years with a major in economics and a minor in political science in December 2003. Her collegiate duration of two and a half years was the shortest time to graduate in the history of Duke. At each stage of her life, her mother warned her that she would someday meet her proverbial Waterloo and at each stage she has avoided such downfalls.

Rousso is sponsored by the PokerStars online poker cardroom under the screenname LadyMaverick as part of their Team PokerStars. Despite the scheduling difficulties of professional poker, Rousso attempts to maintain her physical fitness. Pokerstars approached Sports Illustrated about including a poker player in their Swimsuit edition. Rousso was sent to the Bahamas to be photographed by Sports Illustrated, but she appears in an advertisement in a bikini bottom and cutoff wetsuit top rather than in the editorial portion of the magazine. Rousso announced on her January 4, 2009 vblog that Sports Illustrated asked her to be a part of its Swimsuit Edition and a photo shoot took place at time of the 2009 EPT PCA event in Nassau, Bahamas. Rousso confirmed on January 15, 2009 that that she would appear in the February 10, 2009 issue. Rousso's thoughts on the Sports Illustrated publicity was that "It was a great opportunity for poker in general and for me in particular." Rousso had previously been featured in Maxim, written game theory in American Poker Player, and flown to Las Vegas, Nevada to teach poker to the Forbes 100 Most Powerful Women.
