Is it true that Google reported in 2019 that its Sycamore quantum processor completed a task that would take classical supercomputers thousands of years?

Yes. Google's own 2019 Nature paper reports that its Sycamore processor sampled a circuit in about 200 seconds, a task its benchmarks indicated would take a state-of-the-art classical supercomputer roughly 10,000 years; a reference article repeats that Google claimed this in 2019.
