(If you did the same experiment with, say, only 5 molecules in one chamber and 1 in the other, then while most of the times [on average 5/6] that you tried the experiment you would see the number of molecules in the high pressure chamber decrease and the number in the other increase, if you ran the experiment enough times you would in fact see a case where the 1 molecule in the low pressure chamber went into the high - pressure chamber so that the flow went the «wrong way».
For conduction, which occurs via molecular (or electronic) collisions, you will have collisions between molecules... and the molecules will have a range of velocities but ON AVERAGE, those coming from the hotter side of the object will have slightly higher speeds than those coming from the cooler side and so, in a large number of collisions, the molecules from the cooler side will gain speed on average and those from the hotter side will lose speed on average in the collAVERAGE, those coming from the hotter side of the object will have slightly higher speeds than those coming from the cooler side and so, in a large number of collisions, the molecules from the cooler side will gain speed on average and those from the hotter side will lose speed on average in the collaverage and those from the hotter side will lose speed on average in the collaverage in the collisions.
