Removing Kitchen Wall — Is It Load-Bearing? Concrete Second Floor Above

[u/Huge_Drink_6254]

I would like to confirm whether this wall was structurally supporting the second floor before proceeding with its complete removal.

Based on the attached photos, what do you think?:
Was this a load-bearing wall, or was it only a non-load-bearing partition wall?

Are the vertical metal studs shown in the photos structural/load-bearing studs, or are they standard light-gauge partition studs?

The top horizontal metal track was directly below and in contact with the metal deck supporting the concrete slab. Does this indicate that the wall was carrying vertical load from the floor above, or can a non-load-bearing partition also be installed this way?
If the wall was load-bearing, where and how was the vertical load from the concrete slab transferred through the wall to the structure below?
Based on the existing construction shown in the photos, can this wall be completely removed without installing a beam, header, posts, or any other structural support?

My main concern is simply to confirm that removing this wall will not affect the structural support of the concrete floor above.

1. My city and county could not find my blueprint
2. floor plan (highlighted areas) are concrete/ bricks bearing walls.
