That's what I thought too until I looked it up. It applies to individuals as well.
If an individual runs a web server and processes personal data of individuals within the European Union, then they are subject to the requirements of GDPR. GDPR applies to anyone, including individuals, who processes personal data of EU residents, regardless of whether they are operating as a business or on a personal basis. It's important for the individual running the web server to comply with GDPR's data protection principles and obligations to safeguard the personal data they process.
