Use difference between batch processing delims = and tokens = asterisks

Compare the following two sections CodeDifference in execution results:
1,
@ Echo off
For/F "delims =" % I in (test.txt) Do echo/% I/
Pause
2,
@ Echo off
For/F "tokens = *" % I in (test.txt) Do echo/% I/
Pause

The content of test.txt is ABC. There are several spaces at the beginning of the line.
Are there any differences?

Cause: "delims =" means to cancel the default delimiter, so it will copy the content on the line, and "tokens = *" means to get all content on the line, however, all spaces at the beginning of the line are ignored.
