Should I have a will?

So to start I just turned 25. People close to me have been passing away recently and it really made me think that I should probably have a will sorted out. I have around 110k in stocks and etfs, 10k in precious metals, a work pension/life insurance through my union and a paid off car which is worth roughly 15k. Would it be a waste of money to get a will done? I have a younger sister and 2 parents would my sister be next in kin if I were to unexpectedly pass away? I have lots of questions and unsure where to start.
