Hilinski was named backup quarterback prior to the start of the 2019 season. His first game appearance came during the 2019 Belk Kickoff Game against North Carolina after then starting quarterback Jake Bentley was injured in the game. Hilinski was named starting quarterback later that day. He made his first starting appearance in the second game of the season, a 72–10 win over Charleston Southern. With Hilinski starting, the Gamecocks would set a school record 775 yards of offense, as well as a school record 493 rushing yards. Next week, Hilinski would start in a home game against the Alabama Crimson Tide, a 47–23 loss, where he would complete more passes against Nick Saban's Crimson Tide than any other freshman quarterback.
Hilinski was born to Mark and Kym Hilinski as the youngest of three children in the family. Ryan's oldest brother, Kelly, played as a quarterback for Notre Dame High School, Columbia University, Riverside City College and Weber State University. His second older brother, Tyler, who was also a quarterback at Washington State, died by suicide following his junior season.
