Assuming you have a MacBook Pro Retina, 13-inch, Late 2013, that has two Thunderbolt 2 ports, and no miniDP ports. The plug is identical, the data carried is different. If there are lightning bolts next to the ports, they are Thunderbolt 2 ports:
If so, you can use a Thunderbolt 2 cable (not a miniDP cable) and the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter. Your Mac only supports up to two external displays at up to 2560 x 1600, you will not be able to drive 3 displays. Also, no power will flow back through the connection so you'll need to connect your Mac to AC separately even if the dock provides power over USB-C.
