An unconfirmed status means that the transaction has been successfully broadcasted and it will now find it's way to the different mempools where it will wait to be picked up by miners and included into a block. This is true both for transactions paying 1 sat/vByte and 1000 sat/vByte for mining fees. Bitcoin transactions are not instant (in terms of confirmations) and your transactions can't get its first confirmation at least until the next block is mined. So don't worry about the unconfirmed status.
