My question is can someone who is not well educated (secondary school graduate) understand the statistics of bitcoin investment or Bitcoin trading?
Bitcoin trading or investing is not based on how well your education is, even old people with their bachelor's degrees can't compare to those who trading bitcoin for years. If you want to learn about BItcoin it's better to start now and learn something small day by day along with your native education.
It's good that OP started not to buy first before learning what really Bitcoin is, that's a good move for me because when it comes to investment, cryptocurrency-related or non-cryptocurrency related, it must be always to know first what thing you are investing in, know first where you put your hard earned money. So that in the future, you will not blame other people because of your own mistakes.
