Yes, Most agree that using a secondary fermenter is completely unnecessary and only increases risk of contamination.
Instead, just keep it in primary fermenter for 3-4 weeks, it will suffice. Dont worry, as you brew more and more you will get use out of that secondary fermenter, certain brews need to age longer, you want to add fruit and things and racking to secondary would free up your primary. Certainly as someone new to brewing though, just ignore the step completely.
As far as I can tell, most advise to ignore the time ranges and schedules of any beer kit once it goes into your fermenter.
