5% at most chance of them qualifying. They have to win ALL their games, and they might still not make it on NRR (given how weak their batting is).
if UAE lose all their games and WI win all theirs but lose to AFG, that would leave:
WI - 8
AFG - 6
UAE - 0
ZIM/IRE - one of those teams will win, IRE/SCO - one of those two teams will win.
Yeah there is no way AFG can qualify directly - even if they win all 3 games - unless there are some washouts or in in the absence of washouts, by a very specific set of results and then they still have to use NRR as a tiebreaker.
