RareAirsYes, these are unpowered speakers (except the sub) and must be driven by an amp. The TV will send the raw audio steam over HDMI or optical (TOSLINK) to the receiver, which decodes the audio into individual channels, amplifies it, and sends it to the speakers.
Just make sure the receiver has enough channels to drive the speakers you want to use. If you plan to use Atmos, you'll need a second connection to each of the floorstanding speakers to drive the up-firing "height" woofer/tweeter. Thus, each floorstanding speaker would end up with 2 sets of wires going to 2 channels on the receiver.
