GRANT ALL ON Database.* TO 'AdminPS'@'localhost';
GRANT DROP USER 'AdminPS'@'localhost' TO 'AdminPS'@'localhost';

Answer 1

You need replace only the last line:

CREATE USER 'AdminPS@localhost' IDENTIFIED BY PASSWORD '*CC3DA61A4716581A6A62EE83E5F4119D8C0B5D23';
GRANT ALL ON Database.* TO 'AdminPS@localhost';
GRANT CREATE USER ON *.* TO 'AdminPS@localhost';

As documented under GRANT Syntax:

Table 13.1. Permissible Privileges for GRANT and REVOKE 

+-----------------+-------------------------------------------+
|    Privilege    |                  Meaning                  |
+-----------------+-------------------------------------------+
:                 :                                           :
| CREATE USER     | Enable use of CREATE USER, DROP USER,     |
|                 | RENAME USER, and REVOKE ALL PRIVILEGES    |
:                 :                                           :
+-----------------+-------------------------------------------+
:                 :                                           :
| DROP            | Enable databases, tables, and views to be |
|                 | dropped                                   |
:                 :                                           :
+-----------------+-------------------------------------------+

Therefore, you need to grant the CREATE USER privilege, not DROP.

You need to create your user with WITH GRANT OPTION.

e.g.: GRANT ALL ON Database.* TO 'AdminPS'@'localhost' WITH GRANT OPTION;
