Werner Heisenberg stated that the more precisely the position of some particle
is determined, the less precisely its momentum can be known, and vice versa.
Correct.
This ascribes the uncertainty in the measurable
quantities to the jolt-like disturbance triggered by the act of observation.
Incorrect. You've made the common mistake of confusing the uncertainty principle with the observer effect.
Historically, the uncertainty principle has been confused [6] [7] with a somewhat similar effect in physics, called the observer effect, which notes that measurements of certain systems cannot be made without affecting the systems. Heisenberg offered such an observer effect at the quantum level (see below) as a physical "explanation" of quantum uncertainty. [8] It has since become clear, however, that the uncertainty principle is inherent in the properties of all wave-like systems, [4] and that it arises in quantum mechanics simply due to the matter wave nature of all quantum objects. Thus, the uncertainty principle actually states a fundamental property of quantum systems, and is not a statement about the observational success of current technology
