Yep, it's good

As for, "you've got this", might be bit tricky, as it's an established short phrase in English, which might not be so easy to replicate as succinctly in Irish, but I'm someone will chime in with something.
You could try something like "éireoidh leat/libh!" You'll succeed! (You singular/You plural) Or "Éireoidh go maith leat/libh". It means "You'll succeed" but might be better rendered as "You'll do great".
If you mean it in the sense of "good luck", then an established phrase "Go n-éirí leat/libh" (again, leat for singular you, libh for plural you) would be a solid translation.
Wait for more.
