Yes those are certainly male pollen sacs.
If you have females nearby you need to exterminate them ASAP or risk pollination when they begin to naturally open and release the pollen into the air which will pollinate female plants in the general vicinity.
Won’t be the end of the world but it will give you seeds in your female buds and shift resources to create seeds rather than bud.
Defo a male and 100% passed it onto the other plants. To close together for the pollen not to travel on to the other plants. Unlucky mate just try again gud luck
