Doubts about judging the tinyint field type of MySQL

In writing today SQL The sentence is ,where A... Is used in the condition tinyint Type field to judge , I didn't pay attention to the wrong judgment value , It's amazing that we can find the data

Here is the table and the corresponding SQL sentence

CREATE TABLE `test` (  `id` int(10) NOT NULL AUTO_INCREMENT COMMENT 'id',  `type` tinyint(4) NOT NULL COMMENT ' type ',  `name` varchar(255) COLLATE utf8_unicode_ci NOT NULL COMMENT ' name ',  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;INSERT INTO `test`(`id`, `type`, `name`) VALUES (1, 0, ' name 0');INSERT INTO `test`(`id`, `type`, `name`) VALUES (2, 1, ' name 1');INSERT INTO `test`(`id`, `type`, `name`) VALUES (3, 2, ' name 2');INSERT INTO `test`(`id`, `type`, `name`) VALUES (4, 0, ' name 4');

Perform the following two SQL sentence , The result is the same

select * from test where type = 'type ';select * from test where type = 0;

id	type	name
1	0	name 0
4	0	name 4

I found a similar problem on the Internet , May I have your advice , What's the reason for this ？
