Hypothetical- Gaurenteed profit with sports betting?

[ilikebigbets]

I have a hypothetical question to pose to all and maybe someone can assist me to determine whether or not this is at all possible...

A local bookie that I know has offered me 25% of people's losses that I hook him up with as I am acting as an agent of his, bringing him new customers. So if I acted as my own customer without his knowledge and I lost 5k in week 1, i would only have to pay $3,750 of the losses (this is net losses, so if i won 6k in week 2 i would get the total of 6,000... if the following week, week 3 i lost 1000 i would have to pay it fully, etc.) . My question is: is it possible to bet opposites online at the reliable sportsbook (i.e. pinnacle) that offer -105 lines vs. the bookie's standard -110 lines and somehow guarentee myself a win? Is it possible to give myself a lot of positive ev?

Further, how does this bookie (who has tons of customers) make a consistent profit by giving his agents 25% of net losses and giving 10% to an online service that takes on all of the accounting and receiving of the bets, etc.

Seems to good to be true for me, so maybe someone might/could enlighten me.

Thank you,
