Simplistically, yes. But there are complications which make radio-based networking less consistent than cabled networking. As a friend and I were recently discussing, the optimum environment for WiFi 6E appears to be open offices (bull pens or cubicle farms) with network access points mounted on high ceilings. Line of sight between the radios gets you as close as possible to the maximum achievable data rates. Typical residences aren't optimal, even with mesh routers, though in the few cases I've assisted with, mesh routers are always better for WiFi 5 & 6/E.
When accessing the internet there's more variability, namely the ISP's infrastructure and the cloud servers on the other end of the connection. So the achievable data rates are highly variable if you're downloading or whatever. Data rates greater than 1Gbps are unlikely to be discernible with web pages or streaming. But, yes, for WiFi 6 the internet connection and modem will be the bottleneck.
