Is it normal to have 40 photos with grandmother since teenage years?

I am 24 yo. And I have only 40 photos of me and my grandma since my teenage years. I lived w her these last 2 years. But I didn’t make a video or photo of us. I feel sad. She died 2 weeks ago and I am asking myself: why do I have only 40 photos of us, and much more photos w my friends…
