Me talking at dinner: “Will you pass me the peas?” Cut to 5 people confused about whether I mean just one of them or if I want the whole table to all hand me the peas.

I get why they/them can be confusing because of the plural thing, but we are used to a quirky language. With a little practice, the tone and context clear up nearly all confusion. The rest is as easy or hard as what we have to do with an ambiguous “you.”

PS Sorry to the “yous/yous guys” people. I am not trying to turn a blind eye to you obviously superior usage. It just really ruins my point.
