Whenever you tap a link to open a Web page on your iPhone or iPad it automatically opens a new tab. Having hundreds of tabs open won’t cause any problems but can make working with tabs clumsy. You can close all tabs; touch and hold the tab button and then tap Close All X Tabs.
However, you might prefer to prevent them from building up in the first place. To do that in iOS 13 navigate to Settings > Safari > Close Tabs and choose from Manually, After One Day, After One Week, or After One Month.
