Why does traffic from Google Ads appear when there are no active advertisements running?

My Google Ads have been in pause state for over three months, yet my GA4 reports indicate user traffic under the "Paid Search" category. Are there additional factors within the Paid Search category aside from just advertisements to take into account?

Within Google's documentation, you can explore the specific scenarios in which the tool attributes traffic to Paid search: support.google.com/analytics/answer/9756891?hl=en

If a visitor enters the website via a link that incorporates UTM parameters linked to paid search, GA4 will attribute those visits to the paid search channel, even if you currently do not have active campaigns.
