Hi Daniel! It's great you are considering serving our country as a Marine.
You do not have to go to college to be a marine. However, the paths and pay tend to differ between having a college degree or not. This link should be helpful to you: https://www.federalpay.org/military/marine-corps/ranks . Pay grades beginning with "E" are for enlisted, which primarily for those without college degrees. Pay grades beginning with "O" are for officers who join after college, including coming from military academies. I'm not familiar with Warrant Officers, but looking at the pay in general, some type of post-high school education may be necessary.
Your best bet is to check out the nearest Marine recruiting facility or see if there is anything online that will give you information on the criteria for various roles. My brother was career Army, enlisted, so I'm more familiar with that branch of the military. However, you can't go wrong serving your country in any branch. I salute you! All the best.
