IMO yes, mass attritionable UAVs exacerbates fundemental disadvantage of anti air - hard to defend everywhere vs air power easier to concentrate to create local tactical superiority. Countermeasures can keep pace but doesn't mean they can match scale. It's typically going to be easier to mass UAVs who can use standoff munitions than to preposition defensive assets, especially land based ones, in sufficient concentrations which can be countered by adding more UAVs during mission planning. Countermeasures for high performance UAVs, essentially unmanned fighters instead of low tier drones will be very difficult. Advanced US/PRC HALE drones fly much higher and potentially faster, there's a reason counters like DE or various form of jamming target their ordnances at lower attitudes, not high flying, fast flying drones themselves which still requires combination of high performing ground and air based interceptors that can hit high. Except UAVs can tactically operate without life preservation in mind, which means much more permissive/aggressive operations = even more difficult requirements for counter-air infra. Ultimately it's balance between offense / defensive is matter of industrial base, producing and positioning enough hardware to overwhelm opponents. Effects on battleground will be situational, i.e. large powers can already overwhelm smaller powers, and for peer powers it will be theatre specific, i.e. PRC can more easily overwhelm US carrier groups with mass drones because CSGs has finite VLS cells, power generation etc for defense whereas land based aviation can be massed at scale. Alternatively, PRC's very comprehensive anti-air network might be more easily penetrated by aggressive UAV formations using tactics manned missions won't attempt.
