You have booked for an intermediate station on this train. Therefore you have got pooled quota because on all trains intermediate stations too have quotas for boarding this train to other intermediate stations/destinations. Depending upon how many people book from end to end AND HOW many seats are available to ADI/Surat and other statins enroute for onward journey, you will get confirmed on that basis. This will be known closer to date of journey and probably on charting.
It appears you have not checked availability while booking!
Good wishes.
