In general, load-acquire and store-release memory orderings are required while synchronizing data (that cannot be updated atomically) between threads. In the situation, making counters atomic is enough.

RELAXED memory order is sufficient. For ex: the worker threads are not 'releasing' any data that is not atomically updated to the main thread.

Ideally, the counters should be set to 0 atomically rather than using a memset.

Using the __ATOMIC_ACQ_REL order does not mean anything to the main thread. The main thread might still see the updates from different threads in different order.

Same here, do not see why this change is required.

__ATOMIC_RELAXED is enough.

IMO, the problem would be the non-atomic update of the statistics. So, __ATOMIC_RELAXED is enough

Same here, the problem is non-atomic update of the statistics, __ATOMIC_RELAXED is enough.
Similarly, for changes below, __ATOMIC_RELAXED is enough.
