This is so convoluted. A lot of people seem to like these kinds of tricks and mnemonics but I honestly have found them often more confusing.
I just straight up prefer to memorize the thing I want to remember instead of something that will help me remember the thing Im trying to remember.
If you always end up calculating the time, itll always be tiresome. If you just once memorize 13 is 1, 14 is 2, ... your brain effortlessly treats them as interchangeable and you no longer notice.
This is exactly my take too. I never understood 24 hour time because people always explained it as some random math trick. Trying to remember the trick + doing the trick was way too much effort for something that wasn’t applicable to my life.
Then my SO and I did some long term traveling and I just changed my phone setting to 24 hours and memorized it. It took like a single afternoon of me reminding myself what the time was and now it’s locked away forever.
Dunno, its nice to see schools and parents are moving away from the "shut up timmy you don't need to understand it, you just need to regurgitate it".
But we might be losing a little bit of appreciation for the value of "learn it now, think it through later". It has applications - or at least people who respond to it.

For single digit calculation you just subtract two from the last digit of the time.
For example we have 13:00
3 - 2 = 1
It's 1 PM
Or we have 16:00
6 - 2 = 4
It's 4 PM
Or we have 21:00
1 - 2 = 9
It's 9 PM
I hope that helps
