The average success rate of Colorado elk hunters for either sex, used to be 1 in every 7 years. I don't know what it is now. Elk hunting is hard. You can luck into an elk once in a while, or hire an outfitter, but that is no guarantee.
The group you hunt with is extremely important. You need to have the same drive and endurance. You need to remain positive and not give up. You will get the elk out if you kill one.
Don't feel humbled, it is just learning to elk hunt.
The last 3 bulls I killed were on the last or second last day of my hunt. Two in Colorado and one in Wyoming. I have backpacked all three out, with help.
I would share anything I have learned (for what it is worth). PM me.
