Starting up pros cons and rates

My post might seem stupid but as I enquired about sub work for maritime they have sent me this subbie pack and they’re offering whopping 1.40 a mile I’m running the numbers read number of posts and hardly ever anyone is saying that running a truck on those kind of rates is possible so I’m just trying to work out what is the real deal I know it’s not like I will be a millionaire in a month or even a year but I can’t be this hard to make some money since there are lots of transport companies and more opening every day. I was also thinking of subbing for Gregory’s what’s that like.
