No, they are wosrse.
Gacha games are mostly card-puller games. You pay $X for X pulls, with more expensive packages giving more pulls with a supposed higher success rate of 'winning' (getting a good/rare pull).
They use hidden weights, as well as max item rolls per day. This means that to keep items rare via artificial scarcity they will only allow so many of those cards to be pulled per X hours/days/whatever but they don't tell you this anywhere. So if that new hot card that just dropped is up for grabs, you buy 10 pulls. But you don't know that it's already been pulled X times by other people, so you have literally no chance to 'win'. So those pulls will be wasted.
The companies always lie about chances to win, the pulls are insane, you can see streamers do massive pulls, the numbers are sometimes out there, just community gathered.
A real life example is one of those light-roulette machines at arcaded where you slam the button to stop the spinning light. The only actual chance you have to win is after $X has been spent on the machine, before that threshold has been met winning is impossible, stopping the light at the correct spot won't matter it will simply roll to the next losing light. Or claw machines are the same and will only actually close enough to grab a toy after $X has been spent.
Gambling is one thing but these skinner boxes masquerading as games are pure evil as they change the rules constantly and make winning downright impossible.
