Answer 2

As far as I understand, it's enough here:
UPDATE testbase SET count_clicks = count_clicks - 1 WHERE id = 1 AND count_clicks >= 0
In response, mysql should return an answer about how much the record was changed as a result of the query. If 1 means he is the first, if 0 is changed, then the counter is already negative and he is not the first.
