if someone generated 1000 transactions every minute at zero fee.
Would it mean that anyone else who tried no fee bitcoin would have very little chance of getting confirmed?
Actually it's not possible one from my knowledge.The transaction of bitcoin is confirmed through of blocks and mining.If the transaction is became free,who will do of mining activity.Then overload of transaction happened ,some miners will quit of free mining.This leads to the overload and the time of each transaction of bitcoin will increased to 3-4 per transaction.
