New to bubble: does it fit the needs of my thousand users?

I have a sport App who collect the Match data of its users.
I would like to dynamically send these data to user’s web pages, where, after log in, each user can see their now progress in the sport, with list and graphs.
I am not sure to understand if the Bubble database, behind the web pages, can be written from remote.
Is there an API? Is it a MySQL with external access?
