This is such a silly discussion.

If the question is:

"If bots are able to be made indistinguishable from humans, will it be possible to distinguish between bots and humans?"

then it is obviously truistic. If you extend it over an infinite time period into the future, then, assuming continued technological development, in the indefinite future it will obviously be impossible to differentiate computers from humans.


A far better question is:

"Is it reasonable in the near future to make it massively difficult for bots to play online?"

and then the answer is "Yes." Things such as webcams, developed questions and answers, and so on, will help.
