Huawei smartphones released before the sanction decisions in 2019 still have the Google Play Store installed. Including the P30 models (unless they have the New Edition designation).
However, I do not recommend buying an old phone from 2019.
The Xiaomi Poco F3,released in March 2021, offers a better alternative for less money in every way and it has Android 11 (the P30 Pro only got Android 10). The processor of the F3 is about twice as fast, the built-in storage twice as big with 256 GB, the cameras and the screen are also better. And it can do 5G as well as 4G.
