A native of the Southwest, Ross starred at Hobbs High School in Hobbs, New Mexico. He was an integral part of three consecutive state championships from 1999 to 2001, including an undefeated campaign as a sophomore in 1998–99. Hobbs High School won the 1999 and 2001 state championships at the University of New Mexico's famous home court, The Pit. And while Ross performed well throughout his prep career – having been named USA Today's New Mexico StatePlayer of the Year as a senior – he found himself without any four-year college scholarship offers. In one game that season he recorded 38 points, 8 steals, 8 rebounds, 7 assists and 5 dunks.
College
Ross decided to walk on to the Texas Tech basketball team as a freshman in 2001–02, in spite of his mother's urging to attend one year of junior college instead. It was Bob Knight's first year at Tech and he needed talented walk-ons to begin building his roster. It took until Ross' junior year to earn a scholarship, however. Years later his mother said, "I had to support him. It was expensive and hard at first, but I'd have to say it's worked out." The year he earned his scholarship saw him more than double his scoring average from 4.5 as a sophomore to 10.1 as a junior. He started 31 of 34 games played, and rounded out his season averages with 3.1 assists and 1.5 steals. Knight made Ross a team captain when he became a senior in 2004–05. Ross was known for his work ethic and later that season garnered praise from Knight, who said "He's an all-time example to kids as to what they can do with what they have." He again substantially increased his scoring average, netting 17.5 points per game to along with 5.5 rebounds, 3.0 assists, and 2.6 steals per game. The 6th-seeded Red Raiders advanced to the NCAA Tournament's Sweet Sixteen behind Ross' great play. In the opening round win against 11th-seeded UCLA, Ross scored a then-school record for points in an NCAA Tournament game with 28. In the next round against 3rd-seeded Gonzaga, he scored 24 points, including a go-ahead three-pointer with 1:06 remaining as well as two free throws to clinch the Red Raiders' two-point win. Ross garnered several individual accolades. For Big 12 Conference honors he was named to the All-Big 12 first-team and the All-Defensive Team. Nationally, he was named the winner of the Chip Hilton Player of the Year Award, given by the NCAA to a Division I player who demonstrated outstanding character, leadership, integrity, humility, sportsmanship, and talent. Ross finished his collegiate career with 1,174 points.
Texas Tech head coach Chris Beard offered Ronald Ross a position as a graduate assistant in 2018–19. Beard had been an assistant coach under Bob Knight during Ross' college playing career, and there was much mutual respect. Ross took the position, and in his first year the Red Raiders made it to the NCAA national championship gamefor the first time in school history, but lost 85–77 in overtime. He coached one more season, but upon the conclusion of 2019–20 he resigned, opting to leave the coaching profession to instead to pursue a career in business. He relayed his resignation to the public via Twitter, posting "Coaching has been a blessing and I’m confident in my capabilities to be great at it, but I’ve always been intrigued by business and I’m simply just motivated to conquer a new quest and pursue something different!"
