Is crypto trading not a gambling?

Am curious to know what you guys think .... Is it only me that think cryptocurrency trading is pure gambling. i mean what is the difference between crypto trading and sportsbook gambling? it's easier to say you are a crypto trader than to say you are a gambler. people tend to accept the crypto trader as an upstanding member of the society why they look down on gamblers like the scum of the earth.
I know some people will say they are different but i will like someone to give me a real logical differences because to me the two involves either you lose all your money or you gain big time. Am sure a lot of people will call me an idiot for comparing the two. but like i said, am simply curious and very willing to learn.
I will be glad if people can share there knowledge about what makes crypto trading not a gambling because i have had the argument about these too many times and i haven't gotten a satisfactory answer as to why crypto trading is not pure gambling just like the sportsbook.
