Rim stuff has to do with trueness, which you can get checked at a bike shop. Rotor stuff is separate, I’d check in order: caliper alignment, pad alignment, rotor bolts (if 6 bolt), rotor alignment. OH also make sure your thru axle is fully set.
Edit: wait, scrape on some angles like when the wheel is turning, when you’re adjusting the caliper, or when you’re just spinning it straight?

Normal to an extend. To me it looks more like the tire itself is not running quite straight. It happens and if it’s just that, it’s most likely not an issue. If you’re pushing your maximum tire size though, it could become one. The rotors also often go out of true. You can bend them back straight or just leave it unless you’re experiencing issues with braking.
If it’s not just the tire that’s wobbly but the whole rim, it’s possible to get it trued by tensioning some of the spokes depending on where it wobbles. If you’re inexperienced I’d advise on having a mechanic do it. If you tried it yourself, you’re more likely to make it worse than to improve it.
Edit: check if the tire is seated properly. If it isn’t it’s bad. If it is but the tire just isn’t perfectly round, it’s not so bad

Rotor looks pretty straight , wheel may need to be trued , tire may not be seated all the way or has a slight little bump in it. If youre handy throw a tie wrap around the fork and cut it so it just touches the side of the rim. Now turn the wheel very slowly and see if the rim stays the same distance to the end of the tie wrap or does it wobble back and forth. That should confirm or eliminate the need for truing the wheel. Since brakes are such a safety thing have a shop look at them until you feel more comfortable working on bikes.
