Not at all, but the 1GBps were not the bottleneck until now, but the radio technology WiFi 5 and below. WIFI 5 still worked in such a way that the entire data highway had to be directed from one device to the next, which is very inefficient. With each additional device that connects to the AP, the connection becomes noticeably slower because the device has to wait until the other devices have been served and it is its turn to receive/send data again.
This shortcoming is the reason why WIFIs in public areas hardly work or do not work at all.

With WIFI 6, this should finally change as several devices can receive and send data simultaneously. Thus, WIFI 6 has few advantages in small home networks with few active devices and is even more expensive. Only when the network is scaled up and many clients that support WIFI 6 are within range of the AP(s) can WIFI 6 really show its strengths.

The specification is correct. But of course this access point can only offer 1Gbps. If they were to offer mGE or even 10GE (business area) then the AP would cost many times more. The other side would also have to support this speed, again $$$.
Often many forget that most clients don't come close to that speed. You would have to have a top-end device and stand next to the AP 😊
