You are missing it. <g>

I cannot imagine anyone buying a July 46 call with the QQQ at 42
right now. It would have to move over 10% up (over 46) in a very
short time to be worth anything at expiration. But say you expected a
20% increase to 50 by expiration. The call would then be worth $4.
Your gain would be 4.00 - 0.25 = 3.75 or 15 x your investment
(neglecting commissions) at 0.30 the profit would be 3.70 or 12.3 x
your investment. Whether you paid 0.25 or 0.30 is immaterial. If it
doesn't move up, you lose your 0.25 or 0.30. Not too likely with such
a short time to expiration but probably better odds than a lottery
ticket...

Buying in the money options buys you leverage.

The 38 calls would cost you 4.50 (neglecting commissions). With QQQ
at 42, the intrinsic value is 42 - 38 = 4 and the time value = 0.5
for the total value of 4.5.

A 10% ($4) move in QQQ will result in about a $4 move in the option
price less 0.5 loss in time value by expiration so the final value
would be 8 at expiration. You made 3.5 on an investment of 4.5 = 78%
for a 10% change in the underlying QQQ for a leverage of 7.8 to one -
very similar to what you get with futures - and the most you can lose
is your premium if the market tanks, unlike futures.

This is only two of the simplest uses of options. There are many more
sophisticated strategies.
