A premiere is simply a scheduled start time attached to a video page. The page itself goes up first, sitting there as a placeholder with a countdown, and the actual video does not begin playing for anyone until that set moment arrives, for everyone at once.

Before the start time arrives, the page still works like any other page: people can visit it, like it, and leave comments, even though the video itself has not played for anyone. That explains a premiere page showing a large number of likes or comments next to a view count sitting at zero, since a view only registers once the video actually plays.

While everyone waits, many premiere pages run a live chat during that waiting period, functioning like a waiting room where people trade comments before anything starts. The page description is usually more useful than the counters above it, since it tends to carry the real news: the scheduled time, and often a separate date for a related release along with a link to save it ahead of time.

The practical habit worth building is simple: treat the description as the source of facts and treat the counts on a premiere page as not yet meaningful, since they will only settle once the video has actually played for people. The same setup shows up for countdown livestreams tied to a release, where a page can be up before anything actually airs.
