Correct.  Assuming you use the string-comparison operators (> and <)
rather than the integer-comparison operators (-gt, -lt, etc.).

String comparison.  If you want to do numeric comparisons, use ((...))
or use -gt.

if ((1000 > 200)); then echo pass; else echo weird; fi
if [[ 1000 -gt 200 ]]; then echho pass; else echo weird; fi
