Not only that, bowling is pretty much all math, physics, geometry (angles and such)
Foul line to head pin is the same as pitchers mound to home plate. 60 feet.
The lane is 42 inches wide gutter to gutter.
There is just not enough room to get the ball outside the ten pin to slide it over 42 feet into the seven pin without the ball going into the gutter.
Laws of math say so, it's impossible to make that split (which the seven pin is horizontal 42 feet away) It can't be done that way.
The only way to convert that is with a lucky carom off the wall, or in the above video a lucky carom pin off the bowling ball.
Like I said bowling is all math, movable objects, ball speed of around 18 mph, 18 revolutions or so (amount of times the ball turns over before it strikes the pins) or about 300 rpm's.....
I can go on but I'll bore you to tears.
