Google Play Services is not Google Play Store.

Google Play services is an automatically updated API that Google distributes through the Play Store. It also encompasses some security updates, such as updates to the Bluetooth stack.

You do not need a Google account to update those. In fact, chances are you already got the update weeks ago without noticing.

You can also update pre-installed apps through the Play Store without an account (hold the Google Play icon and select "My apps").

You do not need to install an app. You do not need to make an account. All you need is a QR code scanner and an Android phone that had Google's stuff preinstalled.

I have plenty of issues with the Google Play Store as well, but they don't apply to this topic.
