Keep telling yourself that - don't believe everything the old ballies say at the bar when they want to look like big men, because that's not actually the semantic difference. "Betting" is the specific act of making a contract based on a probable outcome. "Gambling" is the generic term for such activities.
In any case, as for skill - I'd say there is some level of skill involved in spotting the BTC/Crypto trend early and judiciously buying or selling based on your observation of the sentiment and research on fundamentals (just as there is with any other tradable commodity). Personally, I've made in excess of 5000% return in 2-3yrs. Fun fact, I have actually spent ten times more with BTC than the cash I ever actually put in to begin with, and still haven't touched more than 90% of the total original holding.
So yes, I speculate, and I have been lucky, but I also do a lot of research and I'm also increasingly starting to use BTC for making and receiving payments, and you would have to be brain dead not to see how significant this is going to be, or to work out that we're really still in the early days.
Yes, there will be push back from governments and central banks, and one of their strategies will be to try and characterise cryptos as being the realm of drug dealers and money launderers, but actually in the long run there is little they can do to put this genie back into the bottle.
