I removed my chain to change it, and without the free wheel sound i noticed that when i turn my wheel there seems to have a slight rubbing sound, when i look at the break pad, it looks like the left one is way cloaser to the disk than the right one, if not rubbing agains it. Is it normal? if not, how can i fix it. My bike is usable but with that I feel like I am not usin it’s full potential lol
Is it possible that one break pad is always rubbing against the disk?

It is possible and it’s not acceptable. You can center the calipher with likely the two bolts. Or you have to see your calipher how you can center one of the pads. Shouldnt be hard.
Hydraulic disc brakes will self center as the pads wear. I would use a pad spreader. If that doesn’t fix it look to realign your calibers. If that doesn’t work you probably have a bent rotor which in theory you can try and true but IMO there is a good chance it can’t be fixed and you either have to live with it or replace the rotor
Caliper looks far from centred. Remove wheel, with a large flat blade push the pads so the pistons reset. With the wheel still out, GENTLY pull on the brake lever, check that both of the pistons move ok, if not there may be an issue with the caliper itself.
If both moving freely, reset the pistons back once again and replace the wheel, loosen the caliper mounting bolts, spin the wheel, pull on the brake, once wheel stops, hold the brake on, and tighten the caliper bolts.
Check the pad clearance, if it ios not even toosen the caliper bolts slighly enough to be able to move the caliper to even out the gap. Once as even as you can get, tighten bolts fully.
Soin wheel and apply brakes hard a few times, are the pags both clear? If not there is potetially a caliper issue with how much one of them is retracting.
Loosen the Allen bolts on the caliper, squeeze the break to center the caliper, then retorque the caliper.

It’s possible that one of the pistons is sticking, this happened on my disc brakes. It can be cleaned and lubricated with brake oil (Google/YouTube for technique).
