Tesla combines Model 3 and Model Y sales when they report results, so we don't actually know that. According to estimates*, and my own eyes, more Model 3s are sold than Model Ys.
* 2021 is the last year for which Wikipedia has estimates for both vehicles. The Model 3 sold over 1m, the Model Y around 400k.
Right but some countries (incl China) have explicit registration data so these estimates are not a shot in the dark. From Jose Pontes' article where the Wikipedia Y estimates came from, there were 530k 3s sold and 1.2M Ys sold
