It definitely helps any team out, as it can save lots of valuable build time to have a step by step plan with all dimensions laid out, especially if there are a lot of intricate mechanisms in place that must be accurate.

However, one mistake a lot of teams make (ours included) is using CAD instead of actual prototyping, which can create a lot of headaches after the parts are actually manufactured.

Also, in regards to actually learning the software, everything about it is surprisingly intuitive and you will be surprised what you can make. I recommend designing simple assemblies at first and practicing all constraints to learn how they work, then tackle something like designing a previous year's robot to practice for the actual build season.
