Not really, but it probably comes down to how you define terms. If you are considering ARPANET to be "the internet" then you are correct. However, one can argue that ARPANET was just a single isolated network and not really "the internet" until multiple networks were joined via a common protocol. This started happening in 1973[0], the same year the first protobbs, Community Memory[1] came online.

Many would consider the deployment of TCP/IP as the birth of the internet. These protocols were not standardized until 1982[0]. This was well after the first true BBS in 1978[2].
