We have no annual data that far back to compare with. It is an invalid point.
Yes, we don't have yearly resolution but scientists know average temperatures over a century in the past (as you also correctly pointed out), and compared to those we are setting 120,000-year-records.
"Global surface temperature has increased by 0.99 [0.84 to 1.10] °C from 1850–1900 to the first two decades of the 21st century (2001–2020) and by 1.09 [0.95 to 1.20] °C from 1850–1900 to 2011–2020. Temperatures as high as during the most recent decade (2011–2020) exceed the warmest centennial-scale range reconstructed for the present interglacial, around 6500 years ago [0.2°C to 1°C] (medium confidence). The next most recent warm period was about 125,000 years ago during the last interglacial when the multi-centennial temperature range [0.5°C to 1.5°C] encompasses the 2011–2020 values (medium confidence). The likely range of human-induced change in global surface
temperature in 2010–2019 relative to 1850–1900 is 0.8°C to 1.3°C, with a central estimate of 1.07°C, encompassing the best estimate of observed warming for that period, which is 1.06°C with a very likely range of [0.88°C to 1.21°C], while the likely range of the change attributable to natural forcing is only –0.1°C to +0.1°C." source
Note this was for average temp LAST decade. 2023 is ABOVE those temperatures, which is why we beat the 6500-year-ago maximum and the next one was ~125,000 year ago.
