I think even in this case Manchester City's probability is much bigger than inter but to say that Inter doesn't have the power to stop Manchester City I think this is a wrong assumption.
Even though in this case we can also see how Manchester City's current condition doesn't mean Inter can't do anything, it's just that in this case the situation is more difficult for Inter than City but that doesn't mean City can win easily.
Yeah there's always a chance regardless how small or big the probability is, Inter have beat many teams before, if they're weak they wouldn't able reach into final match. We shouldn't underestimate Inter, if the result is draw, the winner will be definitely 50/50 because anything can happen in penalty stage, luck will play. There are many good players missed in penalty.
The chance to play is still 50/50 but for statistics and other things to be honest I still feel Manchester City is superior but I agree with what you said in this matter. As long as they still have the enthusiasm to play even if it's difficult for Inter then it's already very good for them.
They are aware that Manchester City are favourites but that is no reason to be daunted at the moment.
