The advanced feature of giving the notification of a call even before it is actually placed is not just with Truecaller, it is with other apps as well. Like, to register our phone-number on the app, we are often asked to enter an OTP but sometimes the OTP gets auto-filled a few seconds before the text message of the OTP is received on our phone. Truecaller advance message before the call or advance auto-fill in an app before the OTP message arrives is not a technical feature rather, it is the result of a technical race due to the difference in frequency and speed of cellular network and internet network.
