Safe to Update Theme?

Is it safe for me to update my wordpress website theme? I’m using OceanWP and I see that an update is available, but I don’t want it to change the look of my website. I didn’t change anything in the CSS, but I definitely made a lot of changes within the normal customizer. Should I not update the theme if I don’t want to wreck my website?
