The latest default theme is ‘Twenty Twenty-One’. When you install WordPress with default setting, it is this theme which gets installed. This is why it is called the default theme. This theme is installed and used by thousands of websites which is why it becomes the most popular theme. But for many websites, the default theme is too basic which is why it is changed with some other theme. What webmasters usually do is install another theme and then delete all the other theme files including the default theme.
