Photos

Yes. See: See instructions in Set up and use iCloud Photos - Apple Support

If you turn on iCloud Photos on a device, the photos automatically sync with iCloud and with all other devices where iCloud Photos is turned on.

iCloud Photos is a syncing service. Any photo you delete from a device where iCloud Photos is turned on will also be deleted from iCloud and from any other device connected to iCloud Photos. You can potentially reduce the storage space required on a device by turning on Optimize Storage.

A point here is that you don't yourself "upload photos to iCloud"-- you don't drag them to the iCloud icon. Instead, when you tell your devices to use iCloud, they do the uploading invisibly and on their own. You won't see them in your iCloud drive. However, if you sign on to iCloud.com with your Apple ID, then you find all your pictures organized into albums just like in your Photos app.
