i thought so too in the past but then happened this to me in one of the past events:

i posted the 1st picture so that you can see that what's written in the chat behind the screen of lucky * is the same exact thing that you can read in the 2nd picture, where i posted the number of rolls (the 2nd picture is taken actually 5 minutes after the 1st).

consider i'm the 6th power in my server (that's not a dead server, 4 groups in gnw) and usually top 32/64 in my spacetime bracket, so i doubt i may be considered a low power/level.

the problem imho is that lucky * doesn't work in the same way as lucky stars or wheel of fortune. Lucky * is not rigged while for the other two events i can't guarantee.

if we talk about events with a max numbers of rolls per day, like lucky stars or wheel of fortune, i feel like you. If we talk about events with no max number of rolls per day, like lucky *, i think is simply full rng with no advantage towards low power players.
