Not so.
The impactor's velocity was estimated at 20 kilometers per second (12 mi/s).
[29] The
kinetic energy of the impact was estimated at 72 teratonnes of TNT (300 ZJ).
[30] The impact generated winds in excess of 1,000 kilometers per hour (620 mph) near the blast's center,
[31] and produced a transient cavity 100 kilometers (62 mi) wide and 30 kilometers (19 mi) deep that later collapsed. This formed a crater mainly under the sea and covered by 600 meters (2,000 ft) of
sediment by the 21st century.
[32] The impact, expansion of water after filling the crater, and related
seismic activity spawned
megatsunamis over 100 meters (330 ft) tall, with one simulation suggesting the immediate waves from the impact may have reached up to 1.5 kilometers (0.93 mi) high.
[33][34] The waves scoured the
sea floor, leaving ripples underneath what is now
Louisiana with average wavelengths of 600 meters (2,000 ft) and average wave heights of 16 meters (52 ft), the largest ripples documented.
[35][36]Material shifted by subsequent earthquakes and the waves reached to what are now
Texas and Florida, and may have disturbed sediments as far as 6,000 kilometers (3,700 mi) from the impact site.
[37][33][38]The impact triggered a seismic event with an estimated
magnitude of 9–11 Mw .

But do show us your maths for the Chicxulub meteorite having enough energy to destroy the world.
