SQL-获得所有具有1年或以上经验的员工

I've been trying display all employees with their 1 or more year experience , but it keeps showing all , i'm using DATEDIFF(YEAR,Hired_Date,GETDATE()) >= 1 in where clause but even with less that a yr experience, it keeps showing.

员工人数

ID   Hired_Date
001  2018-05-01
002  2018-03-01
003  2020-05-01
004  2019-12-05
005  2017-03-01
