MySQL appears to DROP USER but user still exists in MySQL.users table?

MySQLMySQLi Database

First check all the user and host from MySQL.user table with the help of select statement as shown below

mysql> select user,host from MySQL.user;

The following is the output

+------------------+-----------+
| user             | host      |
+------------------+-----------+
| Bob              | %         |
| Manish           | %         |
| User2            | %         |
| mysql.infoschema | %         |
| mysql.session    | %         |
| mysql.sys        | %         |   
| root             | %         |
| @UserName@       | localhost |
| Adam Smith       | localhost |
| James            | localhost |
| John             | localhost |
| John Doe         | localhost |
| User1            | localhost |
| am               | localhost |
| hbstudent        | localhost |
| mysql.infoschema | localhost |
| mysql.session    | localhost |
+------------------+-----------+
17 rows in set (0.00 sec)

Now, drop the user ‘hbstudent’ from MySQL.user table. The query is as follows −

mysql> drop user 'hbstudent'@'localhost';
Query OK, 0 rows affected (0.17 sec)

Now check the MySQL.user table to verify the user still exist in MySQL.user table or not. The query is as follows −

mysql> select user,host from MySQL.user;

The following is the output

+------------------+-----------+
| user             | host      |
+------------------+-----------+
| Bob              | %         |
| Manish           | %         |
| User2            | %         |
| mysql.infoschema | %         |
| mysql.session    | %         |
| mysql.sys        | %         |
| root             | %         |
| @UserName@       | localhost |
| Adam Smith       | localhost |
| James            | localhost |
| John             | localhost |
| John Doe         | localhost |
| User1            | localhost |
| am               | localhost |
| mysql.infoschema | localhost |
| mysql.session    | localhost |
+------------------+-----------+
16 rows in set (0.00 sec)
