Yes, but the fighter doesn't have it, while all wizards do. I was talking of the spirit of the rules and the general lore of D&D settings, taking also into account past editions (2e and 3e). With the current wording anyone can try the Arcane check, there are no trained only skills anymore.
Anyway the wording was different in the playtest, and we only have a preview now.
I'd point out that this is all PERFECTLY in keeping with 4e's approach. Anyone could use any skill, trained or not, though the DM was within his rights to require training (there was a 'trained only' attribute that a given TASK could have, but not a whole skill). 4e scrolls could be cast by anyone who could make the requisite check(s). Given that the effects often scaled by the quality of the check there were many cases where a PC could cast a ritual from a scroll but had no chance to attain a useful effect in the given situation.
Scrolls do fill a different role in 5e's system, but I think there's at least a residual bit of the 4e "everyone has magical ability" meme left in 5e.
