Correction: A guy hiding in a bush wasn't able to reliably defeat tanks before.
Handheld old anti-tank weapons like RPGs with HEAT warheads were extremely unreliable, defeated by reactive explosive armors, successful only at very close range and so on. Modern ATGMs able to be fired from kilometers away and with >90% kill rates completely changes the dynamic. Those systems are only going to get smarter and cheaper when there is a physical limit on the armor+weight+cost+logistical support equation for tanks.
I would be wary of those numbers. There is a heavy selection bias, as we don't see the videos where the AT weapons fails, where the operator gets shot, etc.
We'll have better information once the fog of war lifts.
