Yes , the variants have unequal chances of survival.
let's take an example....
There are some blue beetles and some red beetles in Forest.
Due to variations the blue beetles changed to green color.Thus is an advantage for them. Because being green in color crows can't see them so they can't eat them.Hence the chance of survival of that particular beetles has increased.

But on the other hand due to variations if the blue beetles turned red, crows can eat them easily and this is a disadvantage for them.

Hence Variation is useful for the survival of species overtime but the variants have unequal chances of survival.

Hope this would help you!

Variations are beneficial to the species than individual because sometimes for a species, the environmental conditions change so drastically that their survival becomes difficult. For example, if the temperature of water increases suddenly, then most of the bacteria living in that water would die. Only few variants that are resistant to heat would be able to survive. However, if these variants were not there, then the entire species of bacteria would have been destroyed. Thus, these variants help in the survival of the species. However, all variations are not necessarily beneficial for the individual organisms.
