Google Chrome Marking Websites HTTPs Secure or not

Hi there,
Yesterday, I got found a security update from Google that it's web browser Google Chrome has been begun marking websites as per HTTPs and secure HTTP metrics. Hope everyone already have idea for this. I searched again on some informative sites and found this article about https://digitalmarketingdailyupdates.wordpress.com/2018/07/25/google-chrome-started-checking-your-website-is-secured-or-not/. I m worried that my website is not secured. I know very well that switching on SSL is the correct way to get secure your website as per Google's terms. But, I think that Google's has been trying to warn those webmasters and publishers to get secure their websites by switching SSL encryption implementation. Also, it could be a ranking factor for websites too in the search engine. As Google already did updated in 2014 as HTTP and was made a ranking factor. What do you think?
Also suggest me best SSL certification provider for my website.

I just use letsencrypt because it's free

I host my sites on self-managed VPS.

Shared hosting was always slower, no matter what my setup was. Getting a dedicated host for a small blog was overkill.

I just host them on their personal vps now and letsencrypt is the best option for free SSL.

This. My sites are hosted on hostgator and 2-3 weeks ago they gave free SSL to all their customers for all sites. I would imagine all/most hosting providers offer free ssl nowadays.
