I am still trying to really figure out how someone else being vaccinated helps me.

No you aren't because the concept of herd immunity isn't very difficult.

No vaccine is perfect. The 80%-90% protection the current vaccines give is VERY good, but still not 100%. But that is just individual protection. Each additional person that has the vaccine (or had COVID and still has some level of immunity) acts as a barrier to spreading the virus. The fewer people spreading the virus, the fewer times each vaccinated individual's immunity is "tested" by coming in contact with a infected person. You extinguish a virus by getting enough people immune.

Why is herd immunity important?
Herd immunity occurs when a large portion of a community (the herd) becomes immune to a disease, making the spread of disease from person to person unlikely. As a result, the whole community becomes protected — not just those who are immune.

Often, a percentage of the population must be capable of getting a disease in order for it to spread. This is called a threshold proportion. If the proportion of the population that is immune to the disease is greater than this threshold, the spread of the disease will decline. This is known as the herd immunity threshold.
