Do I have to be a business to use Search Ads?

Quoting Apple's SA ToC 8.1.18 (emphasis mine):

You agree to provide accurate, current and complete information required to register with Search Ads and at other points as may be required in the course of using Search Ads (“User Data”), including, but not limited to, company name, physical address, corporate payment information, relevant tax information or other information as requested. User Data is subject to Apple’s privacy policy, which is accessible at www.apple.com/privacy.
