Which Raspberry Pi 3B+ GPIO pin is connected to which module in Adeept Motor Hat v2.0?
You've already found the schematic for the Motor Hat.



Now we need the schematic of the GPIO pins of the Raspberry Pi. That's why I asked which one you use. Since AFAIK they are not all equal. RPi 3B+ schematic GPIO:



Now we check the 40 pins, and see if they are equal. And they are! Even the warning in the picture of the RPi is correct in the schematic of the Motor Hat. 

So we can conclude that the module will fit.

Additional comment from OP:


  can you help me with respect to the modules and the pins ie (ultrasonic sensor, line tracking sensor, motor1, motor2, RGB led1, RGB led2). I wanted to know that which module will connect to which GPIO pins so that I can program in python using those GPIO pins ie. when I connect the sensors to the HAT, which pins should I use while programming ? 


You do this by checking the datasheet your link. So for example in the case of tracking, ultrasonic sensor and the WS2812




tracking: connects to GPIO19, GPIO16, GPIO20
ultrasonic: connects to GPIO11, GPIO08
WS2812: connects to GPIO12
