Usually games use UDP, though I guess if the TCP links all get notified of congestion that could effectively ensure there is enough bandwidth available for all the UDP traffic.
most games run at 64Kbits/sec or 120Kbits and FQ helps those "mice" flows a lot, by giving them their own lane.
If also, the greedy protocols like TCP or QUIC back off on filling up buffers (via an AQM) before a gamer would notice (20ms of jitter/buffering is about right, 60ms is teetering on wrong) gamers and downloaders can co-exist happily on the same link.
