Slavery is forcing someone to do labor and not paying them. Slaves are also usually prisoners of war, criminals, poor people, or (as seen in the past with the US) a racial minority. Indentured servants are (traditionally) immigrants who willingly work for people already living in the country. Indentured servants also aren't paid money, but are given food and shelter with the family they work for, and land and freedom after a period of time in exchange for their labor. However, most indentured servants didn't get their land as promised, similar to how some slaves in the US Civil War era were promised freedom after sometime, only to be kept enslaved, or given to another slave owner. I hope this helps!
