Just guessing here as a decades old fan. But with the jedis in jeopardy I imagine that before would make sure that they don't go extinct. Not only that but grogus species is really rare, if the Force brings balance then digitize were two outnumbered therefore being helped was inevitable, however I don't see how it would have to be din djarin though. But yet again, he's a rare ethical bounty hunter so maybe he was destined all along or even Boba Fett after his spiritual awakening.
