I mean, in that sense the efficient market theory is immediately false, since someone must be the first to learn some new information and price it in.
Thing is, the hypothesis can be useful whilst being only approximately true. If it is true to with 0.1% then, in most cases, it is quite appropriate to model it as being perfectly true. And obviously, there are other cases where that model isn't useful. In those cases, it would probably still be useful to take the 0.1% number into account.
