Are transistors that different from one another?
YES - thousands/millions of different transistors with thousands/millions of different characteristics (voltage, current, gain etc.).
I think at your apparently given level of electronic skills you should step back a little and start with smaller devices and get them operating as you intend. Only after that go with the bigger guys.
Otherwise you will be stumbling from one disaster into another one.
And, from a distance it is pretty hard to assist you when you are not sensing what information we need to help you and have to go on a forensic path with you, which will take a very long time until you got all the electronic basics which you don't have (yet).
