Repeating numbers being your higher self/guardian angel/ancestors/etc. trying to communicate is a meme that's been spread around new age groups and which honestly makes no sense. These beings, whether you want to believe they're actually or something else, are incredibly powerful and if they urgently needed you to know something, they'd throw a huge ass sign in front of you or just straight up communicate with you through visions or dreams. 

If you want to gain communication, there are better methods. If you want to learn to read omens, there are clearer things to watch out for. The world is indeed a magical and living place, but just because there are no coincidences doesn't mean that every event is equally important and meaningful.

It's not about numbers, it's about manifesting things into your life. You can choose any type of method, or all of them. Whatever
