No. Anyone who is 18 or who had the opportunity for four years in high school is eligible to attend a community college such as San Joaquin Delta College or Modesto Junior College.
Remember that Community College courses require tuition and assessment tests. Classes that students are allowed to take are based on assessment test performance.
The benefit of taking ABE/HSE courses here is that they will help students improve the skills students need to perform well on the community college assessments or on any other academic assessments.
