Yes, they do, but not all Meta tags can help you in 2019. In my experience, if you want to rank high in Google in 2019 then you also need to focus on high-quality content and user satisfaction.
As a general rule, you should aim for the following character limits within each of your meta tags: Page title – 70 characters. Meta description – 160 characters. Meta keywords – No more than 10 keyword phrases.
Meta tags are snippets of text that describe a page's content; the meta tags don't appear on the page itself, but only in the page's code. We all know tags from blog culture, and meta tags are more or less the same thing, little content descriptors that help tell search engines what a web page is about.
