I disabled third-party cookies option in my chrome browser and yet cookies are being set from google.com and accounts.google.com domain to other sites like upwork.com.

To see for yourself, disable third party cookies in chrome browser -> open upwork.com -> see cookies info.
As per my understanding third-party cookies are those created by domains other than the one the user is visiting at the time. So, why google.com domain cookies are being set on upwork.com?
Update: This issue doesn't happen in Firefox.
Use Firefox. The Web works just fine with all Google tracking blocked.
