Why are there many variants of viruses for example covid it has the delta variant and omicron variant how do viruses mutate and make new variants

A virus is copied, rapidly and in the trillions.
A small percentage aren’t copied properly as a chemical runs out, something is out of position, temperature is wrong, etc.
So it ends up with a small deformation.
Usually this deformation means the viral particle doesn’t work. But sometimes it doesn’t. Sometimes it simply alters the side effects, or the rate it can be replicated, or how long it lasts…
And this small change can make the immune system ‘recognition’ processes not notice it. Sort of like putting glasses on superman to make clark kent.
