WordPress.com is a blog site hosting service by Automattic.
You can get a free blog with basic features. For advanced functionality, you need to opt for one of their paid plans. It can be a great starting point for blogging. If you ever decide to have more control over your site, it’s relatively easy to move from WordPress.com to WordPress.org.
Here are the main differences between WordPress.org and WordPress.com

Small hobby blogs

You can lose your site if you violate the terms and services of the platform
Ads and branding are present on your site unless you pay to remove them
Pricing
