Both LeelaZero and Stockfish 11 think the gambit is sound, moreso than any other gambit if I am not mistaken. Also black can gain an edge against any opening if he plays accurately longer than his opponent no?
First, both the lines you are showing are not the Morra gambit - white tries to return to normal lines with 3.Nf3- and this move order is known to be problematic as 3...a6! gives Black easy equality (4.Nxd4 Nf6 5.Nc3 e5).
Second, and most important, there is no engine which will tell you something useful as early as move two. You are simply wasting electric power to learn nothing.
You’d better hope what I’m saying is true.
I recommend you to start play Open Sicilian with 1.e4 c5 2.Sf3 if you really want improve your chess skill dont avoid it go for it and learn
also play sicilan with black yourself this is a great for chess skill develop opening not easy to handle complicated but also very very interesting . How to crush siclian
