Why Google Search Console is not considering any back-links?

Question

I have written the following 3 blogs on c-sharpcorner:

 

1. https://www.c-sharpcorner.com/blogs/working-with-files-and-folders-in-s3-using-aws-sdk-for-net 

2. https://www.c-sharpcorner.com/blogs/submitting-a-form-to-different-action-methods-in-asp-net-mvc

3. https://www.c-sharpcorner.com/blogs/how-to-define-custom-password-validation-rules-in-asp-net-mvc 

 

All of these 3 blogs, contain a back-link to my website, at the bottom of the page:

Why is Google Search Console not considering the back-links from my blogs? One of these blogs have been viewed 20k times and appears really high in google search result... and it has been around for around 6 months.
