Yes, TLS1.3 cuts out a RTT compared to TLS1.2, but QUIC cuts out another RTT by combining the TCP and TLS handshakes into one. For a full handshake: TCP + TLS

Yes, TLS1.3 cuts out a RTT compared to TLS1.2, but QUIC cuts out another RTT by combining the TCP and TLS handshakes into one.
For a full handshake:
TCP + TLS1.2: 3 RTT
TCP + TLS1.3: 2 RTT
QUIC including TLS1.3: 1 RTT
And for subsequent connections:
TCP + TLS1.3: 1 RTT
QUIC including TLS1.3: 0 RTT (but no replay attack protection)
