If you buy a Farcaster ID # does that become your new #? How does that work?

Don't buy farcaster accounts. You might get rugged. 

They were designed to be easy to use in a social app, not to be traded like nfts. Some tradeoffs we made will make it harder to trade them safely. 

For example, someone can set a recovery address, transfer the account to you and reclaim it back a few hours later.

You basically take over that ID, but you lose all your casts and followers. You can only have one fid per wallet so you’d need to migrate to use the new wallet

my understanding is yes. you switch to that account.
