Farabello is the son of Argentine basketball player Daniel Farabello and moved around growing up to follow his father's career. The younger Farabello attended the NBA Global Academy in Australia, as he considered the facilities in Argentina to be inadequate. He participated in Basketball Without Borders Americas camp in 2017, as well as the Basketball Without Borders Global Camp at the NBA All-Star game in 2018. Farabello committed to TCU in October 2018, citing a strong connection with the players and the coaching staff. He chose the Horned Frogs over offers from Davidson and Cincinnati.
