A child theme in WordPress is a sub theme that inherits all the functionality, features, and style of its parent theme. Child themes are a safe way to modify a WordPress theme without actually making any changes to the parent theme’s files.

When the parent theme gets updated, changes made in the child theme are preserved and applied on the updated version as well.

This is why child themes are the safest and best way to make changes to an existing theme. Rather than modifying theme files directly you can simply override them with the templates in the child theme.
