question about the query

When i run the code without the Where clause I only get 12 rows returned

My question is, in this case, shouldn't it be returning more than 12 rows since I'm not limiting by hire_date anymore?

Here's how i wrote it, simply removed the 'where hire_date > '1999-01-01''

select first_name, count(first_name) as names_count from employees
group by first_name
having count(first_name) < 200;
