In the game rules, 'automatically' means without any further checks needed. So 'automatically grab' would be to succeed at the grab action without needing a check. Much like 'automatically hit'.
I agree with you, which is how the debate started in the first place. With the Remaster rules, strictly speaking, you cannot automatically succeed on a Grab, it has no check. You just do it. And as part of doing it, you make a Grapple attempt as a subordinate action, which means making an Athletics check.
I think the reasonable interpretation is that "automatically" carries down to the subordinate Grapple attempt. My friend thinks if that was the rules intent, they would have updated the statblock when they updated Grab to make a Grapple attempt, and since they didn't, the Grapple check is required.
It the ability didn't just directly apply the grabbed condition the creature would probably always take the other of the two and knock the target prone every time instead.
The Wyvern has another ability that requires it to have grabbed a creature previously on the same turn, so it does have an incentive to grab vs. knock prone.
But I agree with you in that I don't think that incentive merits requiring an athletics check when knocking prone doesn't.
