In the newer versions of Moodle, it does not show the count near the course title.
You will be able to see the enrolled users total count by opening 'Participants' tab in the left navigation panel of your course.
Here, you will be able to view the 'Number of participants' under the search bar/filter.
To keep track, check this number before enrolling users, and then check it once again after enrolments are done.
The difference in the count can be cross-checked with the number of users actually enrolled and to check if all the intended users were properly enrolled or not.
