One of the most important things to understand about transistors is that they are voltage amplifiers, not current amplifiers. Yes a change in base current will give a bigger change in collector current but base current is actually a nuisance, something that we have to put up with. Designers have to make their circuits work despite base current which will vary a lot with teperature and between different devices.
Many people have written that transistors are current amplifiers. They are wrong. Any article that claims this should be taken with a large pinch of salt as the author clearly doesn't understand how transistors work.
