No you can get literally unsolveable captchas with cloudflare. You tick the box and it just refreshes and displays the unticked box again. Or people it on gateway endpoints that just return plain text errors (Humble does this).
There's code that makes it do something different after 100+ failed retries but you can speed it up by editing the _cf_chl_rc_* cookie (which is just a number). I haven't yet worked out what it does differently.
