I'm calling bullshit. TCP has to retransmit lost packets whereas UDP can keep on going without waiting for transmission. Ephemeral data like controller input or past game states can be ignored because that time has passed, while TCP is still trying its best to get the packets there in order and reliably.

Latency is still absolutely an issue. I play games from Japan with my friends in the states and I often have a ping of 140 ms or so. That is latency, and properly implemented games (Rocket League, for example) will deal with it using UDP among other techniques.

Slower paced games can still use TCP though because latency issues are less sensitive.
