Google search console report does not show you, how many pages or blog post are index in Google. It just show you the reports where Google get some query from user, which is matched with your site content and return the results in terms of impression, clicks, CTR, and position.
For example I search on Google "how to remove xyz virus from my computer" and you've write same article on that, then Google will not going to show that article on your analytic report, because your blog post is not ranking in Google first or second page. it is ranked somewhere in 10th page, so on that page, normally people won't go and you don't get any clicks. So such query is not included in your analytic reports. But some popular query Google will show you, so you can improve your article further based on how much impression you're getting.
To know your blog post is index or not, simply type
site:example.com/your-blog-post/ into Google search, and if it return the result then you're fine.
Also I suggest to don't use third party extension tool to get CPC and competition details, because they will grab your data and sell it later. So better to create new person profile in chrome and install there such a tool.
