I've been studying the basics of transistor for an hour now still not understood one percent. Can someone explain me its working word to word in more easier way I am having my exam tomorrow ffs.

its a electric component

Transistor can be your math teacher. Or your school nurse. It begins suggesting maybe you're an opposite sex, after all. Transistor then makes you transit from one gender to another.

Theres many types but i see them as just a switch or a signal amplifier

Bro it's just a logical switch. On (1), off (0).

IQ is 100% genetic.
Grasping concepts is not something that can be taught, if you need extensive help to assimilate all concepts, you will never amount to anything.

Learn a trade, assimilate fully your tasks, and find satisfaction in your mastery of it and of doing good work.

this, it's controlled by weaker electric signals to switch more powerful signals on and off

Its a metal with a narrow gap between its conduction band and 'bound band', s.t. when an electric field is applied over it you can excite the 'bound band' electrons into the conduction band and thus induces a current that has a functional form that resembles a sigmoid function. This is very practical because it allows us to more or less define a binary on/off description to it, and in combinations can be used to create logic gates.

If it's a bjt, you have to understand what a PN junction is. I hope you at least understand that.
A bjt has 3 terminals: base, collector and emitter. The base forms a pn junction with the emitter and it also forms one with the collector.
When the base is at a higher potential than the emitter a large electron current will flow from the emitter to the p silicon in an npn transistor. This is because the pn junction is forward biased. Now, if the collector is at a higher potential than the base then the on junction between them will be reverse biassed creating an large electric field. This field will suck up all the electrons in the p material so an electron current will flow from emitter to the collector.

This is a bit of a simplification. The other anons who were just calling it a switch probably don't know much about transistors. They can be used for analogue electronics as well as digital.
