When using Google Tag Manager with a data layer variable (‘payment_type’), if multiple users on different devices push data to the data layer simultaneously with different values, could this lead to receiving incorrect data in Google Tag Manager when a trigger fires a tag?

I am implementing Google Tag Manager in my app, where I use a data layer variable (‘payment_type’) to track payment methods. When a digital payment is made, I push data to the data layer using:

dataLayer.push({'event':'payment_made', 'payment_type':'digital'});

And for cash payments:

dataLayer.push({'event':'payment_made', 'payment_type':'cash'});

My concern is that when multiple users are using the app on different devices and pushing data to the data layer simultaneously with different values, could this result in receiving the wrong ‘payment_type’ variable value in Google Tag Manager when a trigger is fired and a tag is executed?

Example Scenario:
User A makes a digital payment and pushes data to the data layer.
Simultaneously, User B makes a cash payment and pushes data to the data layer.
If a trigger is activated during this time, could the tag fire with the ‘payment_type’ value from the other user’s transaction?

Does Google Tag Manager handle concurrent data layer pushes correctly so that each user’s data is isolated and accurately captured when triggers fire tags?
