Will I struggle in college if I didn't graduate HS?

I didn't graduate HS because I slacked too hard during my 12th grade year, so I dropped out and planned on pursuing a GED instead. I will be applying for college next year but I'm worried that I might be completely lost and confuse during lecture. College without a doubt is way harder than HS and slacking off will punish your GPA greatly, the teachers or professors won't be looking after you as well, they just want your work and assignments as I've been told. What happens if you don't understand something? What if I come into let's say a biology class room and my mind just go completely blank when I listen to the lecture because I have no idea what they are talking about?

I also find it strange that you are able to apply to college as a mature student at 19 years old with no HS or equivalent diploma, what if you have no understanding of the topic? Do they do a review of HS stuff before they begin like how the teachers in HS would do that for the first week of class?

I just feel really intimidated by post secondary schools, similar to how you would first feel about entering HS after elementary school.
