Definitely yes more people started to gamble because of cryptocurrencies they want to be anonymous and look for convenient while gambling and the crypto gambling sites where giving all those things an anonymous gambler wants.
How far cryptocurrencies have fueled the gambling market is still needing studies to determine the proper statistical data. There is the bullish effect as you speak of but how far these are prevalent in the general propulation and whether they can be extrapolated to the population is still a mystery. After all the overall usage of crypto is also pretty low.
And moreover you can take all the winnings to your home no need to pay any taxes to the government for your balance if you are got it from crypto gambling sites.
You are wrong about this. Most countries have a taxation method of taxing the winning from any casino. Since casinos come under that type of trades group which are bound to get taxed. Evading it can end up in jail.
