Those news headlines are very misleading. Most Tesla's, all BYD's and certain Volvo models are imported from China on large ships so will sell thousands in one month and essentially zero in others. So while the BYD Atto 3 was the best-selling car in a couple of the months of 2023, for annual sales it is well behind the Tesla Y and Volvo XC40.
