Do transactions with low fee chance of getting confirmed increase with time? How does it work are transactions placed in a queue or something?  but if the fee is low wont people jump you in that queue forever ?

If fee is too low, very likely that transaction will not be confirmed. Because miners select transactions that will be included in the block. they select only transactions that increase their profit.
