Ultimately, yes. Or at least try to.
Jerry is enamored with shiny, highly rated first round draft picks, especially those ranked in a similar way on his own team’s draft board. This was a steal of a deal based off of that alone.
I don’t think Jerry would’ve considered this trade if he felt confident in Dak’s ability in the playoffs. Remember last year how he responded after the defeat to the 49ers. That was the second year in a row for Dak where he disappointed in Jerry’s eyes, where he felt the play of other parts of the team were sufficient (e.g., the defense) to win the game.
This is a pure potential move and it may not work out, but it’s chump change to Jerry in terms of risk reward for him. He’s normally a guy who doesn't shy away from high risk and high reward. In this trade he got the potential for the latter without the former.
