At that rate I think you can assume most clicks were accidental.

You don't know my mother

Messages like "Hi I found this podcast episode, you should listen to it!", not fitting her usual or the chat's tone at all. The link goes to the last 19 seconds because she finished listening and the thing tries to be helpful (took me a minute, the first time, to realise she didn't actually mean to share the fragment at that timestamp). At least it matches her native language I guess, looking on the bright side (the message isn't actually in English)

A simple "copy link to episode" button would have been so much more helpful. Not just for me but also any recipients that are as tech-savvy as she is and don't understand why it doesn't show them the whole episode for example, or why it is she's implying it's so important (the template wording is just off because she didn't write it)

I'm pretty confident that my accidental click rate is much higher than one in 476, especially on touch screens, although you'd need to divide that by the total number of links on the page, to get the probability of accidentally clicking on any specific link.
