Theres a text that says purchase battle pass for 1000VP but does this mean that only 1 tier is unlocked? This will be my first time buying something from battle pass so please help me

The reason I'm asking is because I've genuinelly never played a comp game on Fracture, because there's always someone who dodges. ​ I feel like the map looks cool and interesting, but I have nothing other than that to say.
