It looks as if it doesn't play 1.e4 much as white. Since these statistics are for self-play games, that means it won't get a lot of opportunities to play 1.e4 c5 as black. Still, it does seem as if it likes the Ruy Lopez and French better as black than it does the Sicilian. (It would be nice to see a little opening "tree" with move probabilities, rather than this list of 12 most-popular-among-humans openings.)

[EDITED to add:] A couple of other remarks:

Playing against Stockfish, the Sicilian seems to give it more wins as white and more losses as black than any of the other openings listed here.

What's shown here are two particular versions of the Sicilian; for all we know there's a lot more 1.e4 c5 in its self-play than the graphs suggest (e.g., maybe as white it prefers 2.c3 or 2.Nc3 or something). Eyeballing those graphs, these 12 openings account for substantially less than half of AlphaZero's self-play games.

Queen's gambit is there.

That's stunning. I thought that was one of the strongest openings for black.

I thought it was interesting that it seems to like the English Opening. It's not popular, but Bobby Fischer played it in the world championship against Spassky.

Combinations appear in Sicilian often. If you're playing black, that's a good thing depending on your rating.
