>but I've never played any gachas before...
A freshling, my moment to shine! Note: I've only played 3 gacha so far, FGO(hard drop), BA and now Uma, the latter being by FAR the most enjoyable so far! I play everything hyper casually, with a tiny bit of metafagging if the devs generosity allows for it (BA).
In short: Yes, you absolutely can, at least from what I can tell so far.
>saying something about rerolling for some SSR card
They're talking about the "Kita" card, as others already mentioned. It's pretty great, but not mandatory by any means, especially not when you just want to play casually, having at least 1-2 of them is pretty nice though, especially for later.
>you can't do ANYTHING well at all.
Do NOT listen to hyper meta slaves like that, that mindset is going to destroy you!
