It's for all lanes, each lane gets the same number of creeps. However the time it takes for creeps to walk from the Nexus to the lane is different. Basically the outer lanes (top and bot) have a slight delay with the first wave, but after that the waves should have just as much time between them as in the middle lane. This does mean however that the mid lane has a slight advantage because they can farm their wave before top or bot, but this time difference is so small that top or bot should never be more than ~6 creeps behind the mid lane and most of the time should have the same score.

The main reason you lose CS though is through ganks, getting killed, zoned, forced to recall, etc. Unless your enemy is just afk farming it is almost impossible to get 100% of all creeps with most champs. This is also why forcing someone out of the lane is better than killing them but also dying yourself, since it allows you to get a farm advantage. If you're both dead you both stay equal in terms of gold.
