With his victory at PGA TOUR Canada's CentrePort Canada Rail Park Manitoba Open in 2022, joined his fraternal twin, Pierceson (Korn Ferry Tour), and his grandfather Charles (PGA TOUR and PGA TOUR Champions) as a winner on one of the PGA TOUR's affiliated Tours.

Both Parker and his twin brother, Pierceson, (who is 37 minutes younger than Parker), are third-generation professional golfers, as their father, Kyle, played collegiately at University of Texas (1983-87) and made over 20 Korn Ferry Tour starts from 1990-96, and grandfather, Charles, played on the PGA TOUR from the 1960s through the mid-1980s, winning three times on TOUR, including the 1971 Masters Tournament.

Father, Kyle, also played the Asian Tour and Canadian Tour and Korn Ferry Tour. Grandfather, Charles, played on PGA TOUR Champions following his PGA TOUR career.

While at Plano (Texas) West High School, won a team state title in 2016 and individual state title in 2017; he joined his grandfather, Charles, as the second Coody with an individual state title (Charles won the 1A state title at Stamford High School), while he and his twin brother, Pierceson, followed in the footsteps of their father, Kyle, with the team state title, as Kyle and four-time PGA TOUR winner Bob Estes led Abilene Cooper High School to back-to-back 5A team state titles in 1982 and 1983 (Estes won the individual title and Kyle finished second in 1983).

In his grandfather Charles Coody's final appearance at the Masters in 2006, Parker and his twin brother Pierceson (both age 6 at the time) caddied for Charles in the par 3 contest. The twins putted on alternate holes, with Pierceson making a 40-footer on No. 9.

Along with his twin brother, Pierceson, broke a bone in his arm during a non-golf-related relay race, smashing into a padded cement wall, using his arm to lessen the impact. Was sidelined for two months.
