AWS x64 'cores' are the virtual cores you see on hyperthreaded CPUs and map 2:1 to physical cores on the CPU, but the AWS ARM offering doesn't have hyperthreading, so the virtual cores map 1:1 to cpu cores.

You can disable hyperthreading on the x64 instances at the cost of halving the number of cores you have available in the instance that you paid for.

Yes, but this doesn't really matter - just multiply the cost by two in your accounting. Its not like you one get one core with 15 hyperthread cores
