The iPhone was in construction sites and the screen was shattered and I wonted to know if I’m using the phone and I drop it will I stop working since the phone was broken before

Hard to answer without being a wizard, some phones fall tens of times and still work, others get broken with just one bad fall. Try not to drop it and buy a strong bumper cover and a tempered glass to protect your screen if you know chances it may fall are high.
