You definitely shouldn't worry about the time to get your license. As others have said the number of variables that affect this can mean that a 'bad' pilot gets his license after 45 hours and a 'good' one after 90.
A lot of what delivers a quick pass is aptitude and regularity of training. But when you get your license there should be very little difference between your ability and judgement compared to any other recently qualified PPL, irrespective of how long it took you to pass. If you pass, you are good enough to be let loose on your own.
BTW: I passed my PPL in 1981 (aged 17) when it could be done in 35hrs. I took 38, but had gone solo in under 6 hours. Time to solo means nothing. I understand that time to solo is very age dependent.
Good luck with the PPL.
