I don’t really use the 👌 gesture except from when I’m in China because they seem to recognise that one more than a thumbs up. As for 14 and 88, I was a 14 year old once but not quite 88. I don’t know what you’re getting at. I know the Chinese also use 88 as a representative of marriage… Along with 999 meaning something and I think I saw a 666 in China as well.
