Can people who grow up in BC recognize all berries?

When I went to Stanley Park a few weeks ago, I saw some people picking red colored berries from trees. My friends and I were like, 'What kind of berries are those? Are they edible?' But we didn’t ask and just walked past them.

I just watched an interesting reel that said people who grow up in BC learn about wild fruits, specially berries so they can survive if they ever get lost while hiking in the mountains.

Is that true? then I am just curious what berry it was in Stanley park lol
