No loss in energy due to collision is for elastic collision.
But there will be a loss during collision in case of in-elastic collision.
So KE will remain constant before and after collision in case of elastic collision.
Because in physics the definition of an elastic collision is one in which the total kinetic energy (of the bodies involved) is the same after the collision as it was before hand.
In the case of a rubber ball hitting a wall some of that kinetic energy is lost due the ball deforming on impact (which manifests as heat - although not in quantities that are easily noticeable).

In an elastic collision, no kinetic energy is lost, and the relative speed of separation of the objects after the collision is the same as the relative speed before the collision. In an inelastic collision, part of the elastic energy is lost, and the relative speed after the collision is less.
Elastic Collision is the collision in which colliding objects rebound without lasting deformation or heat generation.Inelastic collision is a collision in which the colliding objects become distorted and generate heat during collision and possibly stick together.
When the collision is perfectly elastic then energy is not lost but exchanged between the bodies collided. So total KE would remain the same before and after collision. But in case of inelastic collision, there would be loss of energy in the form of heat or sound or vibration etc etc. But whether collision is elastic or inelastic the momentum is conserved. That is, the total momentum in a given direction would be the same before and after collision.
In an inelastic collision, part of the kinetic energy is absorbed by the colliding objects, and converted into heat. For an inelastic collision to occur between molecules, the energy would need to be absorbed at some lower level.

difference between elastic and inelastic demand
Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.

its a collision

just check momentum before and after and if they're the same then elastic if not then inelastic.

Momentum is conserved in both elastic and inelastic collisions. Mechanical energy is conserved only in elastic collisions. In inelastic collisions, part of the energy is "lost" - usually most of it would be converted to heat, eventually.
The midpoint between elastic and inelastic is unit elastic
elastoc collision because they can stick together
