That's my understanding, yes. I could be mistaken.
From the WTF website and its tournament rules,

Article 4, Paragraph 1, page 8:
1 Qualification of Contestant
1.1 Holder of the nationality of the participating team
1.2 One recommended by the WTF National Taekwondo Association
1.3
Holder of Taekwondo Dan/Poom certificate issued by the Kukkiwon or WTF
1.4 Holder of the WTF Global Athlete License (GAL)
1.5 Contestants at the age of at least 17 years old in the year the pertinent tournament is held (15-17 years old for
Junior Taekwondo Championships and 12-14 years old for Cadet Championships). Ages for Youth Olympic
Games might be different depending on the decision of the IOC.
These qualifications apply to these types of tournaments:
1 The Competition Rules shall apply to all the competitions to be promoted and/or organized by the WTF, each
Continental Union and member National Association. However, any member National Association wishing to modify
some or any part of the Competition Rules must first gain the prior approval of the WTF. In the case that a Continental
Union and/or a Member National Association violates WTF Competition Rules without prior approval of the WTF, the
WTF may exercise its discretion to disapprove or revoke its approval of the concerned international tournament. In
addition, the WTF may take further disciplinary actions to the pertinent Continental Union or Member National
Association.
2 All competitions promoted, organized, or sanctioned by the WTF shall observe the WTF Statutes, the Bylaws of
Dispute Resolution and Disciplinary Action, and all other pertinent rules and regulations.
3 All competitions promoted, organized, or sanctioned by the WTF shall abide by the WTF Medical Code and the WTF
Anti-Doping Rules.
