Are dynamic arrays actually dynamic?

I'm reading about dynamic arrays (specifically at https://www.learncpp.com/cpp-tutorial/dynamically-allocating-arrays/), and it seems to me that dynamic arrays are not actually dynamic, in that the size allocated for them cannot be changed. If I am understanding correctly, the main use or point of dynamic arrays vs fixed arrays is that dynamic arrays will be allocated on the heap rather than the stack, and therefore can be larger. The terms "dynamic" and "fixed" give me the impression that one can be changed and the other cannot, but it doesn't seem to be the case.

Is this correct, or am I misunderstanding something about dynamic vs fixed arrays?
