Is this seen as a replacement/competitor for ChaCha20 that has NIST approval? Trying to figure out the impact here.

No, this is a lightweight block cipher, requiring low resources. ChaCha20 is a stream cipher based around 64 bit operations and a large internal state. Ascon is more a replacement to AES with a suitable authenticated encryption mode.

ChaCha20 is an ARX construction. Ascon is Sponge construction (more akin to Keccak and all its versions and friends)
