Drag the application from your applications folder into the trash. Empty the trash.
If you are extremely picky about uninstallations, which you shouldn't, then you can use AppZapper.
Is it really that easy? Windows is such a pain in comparison.
Appzapper probably takes up as much space as a year's worth of these files.They do not degrade system performance but over time they do take up unnecessary space. you could try appzapper or cleanapp. Both have trial versions available. Once you have used one of those apps, use finder to search for any other files the uninstallers may have missed
