They are not the same.

In mountaineering, if something goes wrong, you could die.

In base jumping, if you don't do everything correctly, you will die.

A bit like the difference of a car engine failing (it will roll to a stop) vs an airplane engine failing (you will come down hard on the ground)

An engine failing on an aircraft, especially a light aircraft, is not a guaranteed crash landing. It is a serious situation, however aircraft usually glide well. This means you have opportunities to find somewhere that is adequate for landing. Many aircraft with engine failures have landed safely on airstrips. Interestingly this is also the case with helicopters due to their ability to autorotate.
