How to find the position of a user in the database?

Question

MySQL

Good afternoon. Help to make correctly request SQL.
There is a table:
id | user | count
in User - specifies the user ID.
in Count - indicates the number of actions performed by him.
I want to get a complete table sorted by count (who performed the most actions), and at the same time find out what position a certain User is in.
To get the list, I make a request:
SELECT * FROM `stat` ORDER BY `count` DESC
how can I find out the value for the user user = 25 for example?
