If you can do an additional year in high school I can only see it helping you, not hurting. Your English will improve, you’ll have time to look more extensively at colleges, and your family can save up more money.
If not, it will be up to you whether you prefer a Gap Year to do the above, start at a community college looking to transfer, or try applying and see what happens.
How good are your computer skills now? Did you find out at what level your folks can afford college? It’s anonymous here, so offering a range is good enough, not any exact finances, eg, can’t afford anything, can afford 10/20/30/40K annually, can be full pay, etc.
