Sterilizing Mason Jar for Oat Yogurt?

Making homemade Oat Milk into Yogurt for the first time! Unfortunately I made an oversight and pulled a Mason Jar out of the cabinet and just washed it with soap and hot water let it mostly air dry, then added my cooled down mixture of Oat milk (boiled to 180f + tapioca starch & coconut oil), let it cool and then added probiotics. Planing on letting it go for 12-24hr.

Is this unsafe and am I talking a large risk here by letting this culture without technically sterilizing the mason jar? I assume this can’t be as risky as animal derived milk, but I have no idea, and don’t want to cultivate bad bacteria or something toxic.
