An airspeed indicator works so well because it directly measures the difference between static and dynamic pressure. It uses this data to DISPLAY a measure of airspeed. ...
Not really, an ASI measure the difference between TOTAL pressure and the STATIC pressure, i.e, the DYNAMIC pressure.

Tbe ASI shows the Indicated Airspeed, including corrections for position and losses in the system.
Measuring total and static pressure is usually done upstream of the indicator, at the sensor, for these reasons.
