I found that in 123, d matches 1 and 3 but not 2. I was wondering if d matches a digit satisfying what kind of requirement? I am talking about Python style regex.

Regular expression plugin in Gedit is using Python style regex. I created a text file with its content being

123

Only 1 and 3 are matched by the regex d; 2 is not.

Generally for a sequence of digit numbers without other characters in between, only the odd order digits are matches, and the even order digits are not. For example in 12345, the matches are 1, 3 and 5.
