Not the same size, the comparisons are misleading as both those phones look small compared to the 13 max. The SE has a form factor that matches many Android phones, small-phoners (like me) want to go smaller than that if possible.

I had the previous SE from years back and it's still my preferred size, the current mini is significantly bigger than it.
As an aside, I had to switch to the 12 mini as the old SE started becoming unusable due to its age. I did switch to a Pixel 4a temporarily but that was too big for what I wanted and traded it in as soon as I could.
Well, it's up against the iPhone SE, which has the same size, same weight and the same processor. [1]
