We've talked a lot about Google HTTPS over the years and truth is, it seems the ranking benefit is too small to migrate to HTTPS just for that reason. In any event, I migrated this site and others to it and I also launch new sites under HTTPS, because it is easy.
But what has been the adoption rate of HTTPS over the years?
ahrefs did a HTTPS study that analyzes the top 10,000 domains and it showed that "60% of the websites tested have no HTTPS whatsoever" and "only 1 in 10 websites has what we consider a flawless HTTPS setup." You can get more stats at the link above.
So when someone questions Gary Illyes about this, Gary from Google responded that " it's more important to have the sites people actually use to be https. Not all live domains are actually sites."
Next he said that he will try to give us stats on this from Google's perspective. He said:
@legosystem it's reasonable. I'll try to get some of these stats public in the next few months

That would be awesome!
