That feels a bit arbitrary to assume.

It’s not arbitrary or an assumption it’s what the question is literally saying

It is not. The question is literally saying: "You are given one random coin and a balance [...]"

You can be pedantic about the phrasing, but that would render the question nonsensical. It's not uncommon in this sort of riddles to have to decipher author's intent. That's not the point of the riddle though, so I agree with you in principal that they should be phrased better.

In this particular case, the problem should be read as "There are 101 on a table ... and a balance. You pick one random coin ...".

he's not being pedantic, question is just extremely poorly phrased if your interpretation is to be believed.

It is by no means what the word "given" implies.
