"They" is very rarely ambiguous because it is almost always contextual. It's been used as a pronoun for unknown or ambiguous gendered subjects for a very long time!
But that usage was a bit different. They has for a long time been used in the singular but generally only to indicate an unknown person, and generally in contexts where it was unlikely to cause confusion, with something like 'he or she' substituted if using 'they' was likely to cause confusion. 'They' was (quite rightly) not generally used to refer to people whose identities are known (other than very occasionally if you didn't know enough about the person to know their gender). That usage, where you refer to someone you know as 'they' purely because that person has demanded it and claims to take offence if you don't refer to them as 'they' is completely new (and to my mind is plain wrong).
1) "I have forgotten my ticket and will go and see a ticket clerk before I travel to get it sorted - I hope they're helpful!"
Yes that's a good example of using 'they' to refer to a completely unknown person - as has long been the case. Notice that in this example, the context makes the plurality completely unambiguous - which is one reason why it's long been fine and correct to use it here.
2) "Why do they always fine me when I can't present my railcard on the train?"
I don't think that's quite the same thing. In this case 'they' arguably refers to the organisation doing the fining, and therefore is correctly referring to multiple people.
3) "I saw Jamie earlier as I heard they were upset - they were fine, but I've seen them have better days"
Yes, this is an example of the very new usage that has come about purely as a result of trans activism and which I would argue is wrong. This sentence would not have been written - say - 20 years ago, unless you actually do not know whether Jamie is a man or a woman.
"They" is a fixture of the language and you may as well start getting cross and uptight about the people who use "they" in the second example because it's not entirely clear who "they" are unless you have the context either.
It's not so much about getting cross about it, as about that people who insist on using 'they' are in one small way making English language less precise and more ambiguous - and therefore in some cases making it harder to express precisely what you mean. That is objectively a bad thing.
