`noatime` mount option's effect on `stat` access time

I have mounted ext4 partition in Ubuntu 20.04 with noatime mount option in my /etc/fstab From stat: Access time doesn't change when the file is opened on the editor or modified and saved, while modification time changes. Even when the file is repeatedly modified and saved, closed and saved the Access time doesn't change. So, when does Access time change in noatime mounted partition? Does it ever change? Does it represent the creation time (in noatime) or when it was copied to the partition?
