I read this article https://marketing.adobe.com/resources/help/en_US/mobile/android/metrics.html but I couldn't get the difference between very similar metrics as e.g. First Launches, Daily engages users, Monthly engaged users etc and First time visitor, Daily unique visitor, monthly unique visitor... Are they not the same? 

If I compare them in the Key metrics report, the numbers are totally different: On one day I have 3 times more Daily unique visitors than Daily engaged users. Or I have almost double 1st Visits than 1st Launches... How is that possible? Shouldn't the numbers be exactly the same?

(I'm referring to Adobe Analytics.)
