Does GDPR apply to non-EU citizens?

Yes, it applies to non-EU citizens under certain circumstances. The regulation is designed to protect the personal data of individuals within the EU, but its scope extends beyond EU borders. It applies to any organisation, anywhere in the world, that processes the personal data of individuals in the EU. This includes non-EU citizens who are in the EU at the time of data collection.
