I love Minecraft! I started playing at the start of lockdown as my 6yr old grandson is in to it BIG time and we can play together whilst chatting over Discord which has been a really wonderful way of keeping connected when we weren't allowed to see each other.
Starting on creative mode is a good way to start to learn how to do stuff as everything is avilable to you and you can fly! I have a large creative world now which allowed me to build up my skills, then I set up a Survival world - thats harder as you start with nothing, and things try and kill you (unless you set it to peaceful mode). I now play almost exclusively on Survival as I find it far more satisfying to work out how to do stuff myself and earn the tools for the job.
I thought it was a steep learning curve myself - a lot will depend on where you are playing the game (desktop/laptop/xbox/tablet/phone etc.) what "platform" you are on determines which version of the game you have and you need to only watch youtube guides that apply to YOUR version of the game (I play Windows version which is equivalent to Bedrock or Minecraft P.E.). I also use an Xbox 1 controller which is MUCH easier than using keyboard commands.
Some of my first efforts I did video walkthroughs of which I uploaded to youtube and which caused a lot of hilarity for my grandson (Nana getting chased by polar bears for example). Now my grandson proudly says Nana knows more about Minecraft than his daddy does!!
Easy thing to start building in creative are small farms, or pixel art "statues" I've got my own "land of the giants" filled with statues of Lego Batman & Robin, Ironman, Spiderman, Super Mario & Luigi etc. thats a lot like doing counted cross stitch using the blocks.
Persevere it really IS worth it.
