How do you define a rookie

How do you define a rookie? :

A player that never touched Valorant before

A player that played in tier 2 and got accepted in Tier one

Just curious

first year of playing in tier 1

Both are acceptable conditions

Probably someone who's new to tier 1 VALORANT, but also doesn't have any significant tier 1 experience in similar FPS games such as Counter Strike

A player who is playing in tier 1 valorant for the first time. Doesnt matter he has come from tier 2, ranked or through any other path

First is a newbie - new to the game
Second is a rookie - new to the sport
