For standard TCP/IP yes.For instance an Intel NIC? Not factoring in any software bloat or background processes
If you're doing LAN stuff that you want to opimize you might opt for 9000 MTU or jumbo frames, which can reduce that 5.5% overhead significantly to be under 1% overhead instead, getting speeds much closer to "true" gigabit.
But consumer WAN connections are almost always the default 1500 MTU which results in a 5.5% overhead making the maximum possible speed ~945mbps, and for most LAN use cases, 945mbps is more than enough, it's really only worthwhile chasing that last ~35mbps if you're doing LOTS of bulk LAN file transfers or similar.
