Curve parameter is an abritrary number parameter used to evaluate the cunction that describes the curve in 3d space. If you integrate this function of the parameter over it's valid domain, you get the length.

For linear segments the intgral is just the product if a unit vector and the parameter domain. So length and parameter are equal.

This is not true if you reparametrize. Then the curves parameter domain is set to [0 to 1] regardless of the curves type.
