If it goes to the site account then they would take their fees for mining and then withdrawal fees leaving really nothing left.
Am I correct in thinking this?

eobot as the oldest cloud mining is working fine and they are still legit until now, but to get roi with them, its need a long time almost more than 1 years. i don't recommended to use their client software because they are not update the software but if you have hardware mining like s7 or s9, then you can mining with eobot but i think its better to mining in other places with your s7 or s9.
the coins will remain in your wallet in your eobot account and still there until you decide to make withdraw. you are right that they would take their fees for mining and then withdrawal fees leaving really nothing left.
