First ride puncture from a sharp gravel. Just unlucky, or tubeless required ?

Hi guys, posted about my NBD on my Grizl CL SL 7 trail this morning, doing my first 30km.

I had the bad surprise to get a puncture by a small but sharp gravel. I was riding on rather clean roads or cement path in forest, not some wild adventure on crazy rocky path. I used to ride those paths with my pretty cheap and 12 year old teenager mountain bike with Hutchinson python tire and never had any flat tire.

The Grizl has Schwalbe G one bite tire, designed for gravel, so I’m a bit surprised to have a flat tire with such a small gravel.

Am I just unlucky, or this kind of tire absolutely need a tubeless mounting ? I never did this before but I might try if I get a puncture every ride 😅

Thank for your help
