Is it pure luck?

All I did was I opened the tile showing 4. Watch what happened in the next 6 moves...



Let's find out the possibility of this:
4/8 * 3/7 * 2/6 * 1/5 * (51-4)/(16*16-3*3) * (51-5)/(16*16-3*3-1) =
1/2 * 3/7 * 1/3 * 1/5 * 47/247 * 23/123 =
3243/6380010 =
0.00050830641331283179806928202306893 or
0.050830641331283179806928202306893% or
1 in 1967.3172987974098057354301572618

Quite amazing.
