The odds are set before the spin

A gacha draw is usually a random selection from a pool of possible rewards, with each item assigned a probability. Rare characters occupy only a small share of that pool, so a player can make many draws without receiving one. The animation may build suspense, but it does not change the underlying odds.

In many systems, each draw is independent: missing a character once does not make it more likely to appear on the next try. A sequence of near-misses can feel like progress, even when the probability has reset with every spin.

Why duplicates still have value

A duplicate is not always treated as a wasted result. Some games let players use extra copies to strengthen a character, unlock upgrades, or exchange duplicates for another in-game resource. That gives even a repeated reward a possible purpose—and can make collecting multiple copies part of the progression system.

The tradeoff is that a player seeking one particular character may receive other items repeatedly while the desired one remains elusive. A large reward pool makes that mismatch more likely: the game can award something rare without awarding the specific rare item the player wants.

The design keeps the next draw tempting

Random rewards make each draw uncertain, while limited resources—such as earned currency or paid tokens—make the choice to keep drawing consequential. Some games add a guarantee after a set number of attempts, often called a pity system. It can put a ceiling on how long a player waits, but the guarantee’s terms vary, and it does not necessarily make every earlier draw more likely to succeed.

That combination of suspense, repeated chances, and duplicate-based upgrades helps explain the cycle: the next draw feels meaningful because it might resolve a specific goal, even when the odds have not changed.
