How to count the number of published posts
The term "number of published posts" refers to only the number of items published as the model post type.
In this case, the number of published posts in the bottom left area of your dashboard is two because there are two items whose status is "published."
The numbers of Items that you can publish for the User Type, Category Type, and Custom Type models have no limit to any plan.
