Firstly, at this point in the Star Wars galaxy, not much is known about the Jedi. For people like Din and other characters in The Mandalorian who weren’t privy to the events of the Skywalker saga, the Jedi are almost like mythical creatures – even the Armorer, who has some knowledge about them, doesn’t seem to know anything more than what she told Mando. Given this, Din is seeking out other Mandalorians who might have a better idea about where he can find the Jedi. Secondly, since Mando himself barely knows anything about the Jedi, it’s possible that he’s also being cautious about the possibility of simply handing Baby Yoda to them. Learning more about them first through his people would be a smarter way of going about with things rather than seeking them straightaway without having an idea of what to expect.
It’s worth noting that at this time, Sabine (a Mandalorian) and Ahsoka Tano (a previous member of the Jedi Order) are supposedly still looking for the missing Ezra Bridger (Jedi Padawan). At least the first two of those characters are supposedly appearing in The Mandalorian season 2, as well as Boba Fett (Temuera Morrison) and Bo-Katan Kyrze (Katee Sackhoff), so it’s possible that Din’s quest to find his fellow Mandalorian results in his encounter with them. Among all those players, Ahsoka’s involvement would be the most important since she can shed a light on The Child and his connection to Jedi Grandmaster Yoda, but it’s through the Mandalorians he can find the Jedi.
