UIUC does not use “level of applicant’s interest”, according to http://www.collegedata.com/cs/data/college/college_pg02_tmpl.jhtml?schoolId=982 .
However, general admission stats do not capture the fact that UIUC and other schools have different admission buckets, such as in-state versus out-of-state and majors or divisions of different levels of selectivity. The OP is out-of-state and applied for what is probably UIUC’s most selective major (CS), so s/he may be facing a much higher barrier to admission than someone applying for one of the many less popular majors. Be very careful about assuming that a school can be a safety if applying for a popular major at a school that admits by major.
Looks like the OP already has two admissions, which are safeties if they are affordable. However, both do require a secondary admission process to enter the CS major. However, it seems odd that the OP did not apply to a larger list of UCs and CSUs to reduce the risk of being shut out of the relatively inexpensive good choices available to a California resident.
