when we use drawing softwares (like Photoshop, Illustrator), is t predefined for us and the curve changes as we moved the control point around?

The smoothness of the curve changes as you move p1,p2 around. t is a variable for interpolation so the designer never sees it. The algorithm is evaluated at different values of t in order to draw the final curve. It's like the "i" variable in a for loop :)

I see. Do you mean the curve is evaluated at many ts before it finally comes to the curve that we see on the screen?
