I'm fairly new to valorant but every game someone always asks "you got a vandal skin?" and I don't get why people are going crazy over it. is there an advantage to skins other than they look cool?

Uh we were winning 11-10 and viper ults 11-11, then she ults AGAIN the next round 11-12 and then we lose the match, so in total she ults thrice, I think this is not possible or is there some shady tactic that we don't know of?
