Hello i want to ask apikey in themoviedb is public or private?

Your API Key is Private.
Only you and Travis Bell, the administrator, can know which one it is.

If my apikey is exposed to the public, what impact can it have?

The impact occurs if someone steals your API Key to use it illegally.
Your API Key may be cancelled.
