No- in Orthodox Judaism, we believe you don’t need to be Jewish to earn your place in the World to Come, and you don’t need to be Jewish to have a meaningful and close relationship with Gd, and to live righteously. You just need to keep the 7 Noahide laws. We consider there to be many pathways to becoming close to Gd - even within Judaism there is a lot of different ways of living and observing.
We don’t actively seek to convert others, because we don’t believe that being Jewish makes someone ‘better’ or that they need to be ‘saved’. We believe that the Torah was offered to our ancestors, and we undertook and accepted to keep its commandments. But that doesn’t mean we think only our way is right, or superior, it’s just that keeping the Torah is our role and responsibility. This is where the idea of being the ‘chosen people’ comes from. It’s a role, not a rank. Every nation and people have their own purpose, and the Jewish people have theirs.
Also, converting is considered irreversible; once you’re Jewish you’re committing to taking on the responsibility of keeping the Torah and the 613 (plus more!) commandments. If someone converted and then it became too much, they’d still be Jewish, so would be transgressing the commandments . Converts are discouraged until it can be seen that they really are serious and genuine about their commitment; they need to go in with their eyes wide open. It’s made hard at the outset because it doesn’t get easier after. Plus they are taking on antisemitism - I don’t mean this lightly- historically, a convert would need to understand that joining the people means they would face the same persecution, pogroms, libel etc as everyone else. If someone really is drawn to Judaism, though, and feels it’s right for them, they can convert, and once you’re in you’re in - King David’s great grandmother was Ruth - I.e our royal line descends from a convert.
