No matter how good you are in technical analysis and fundamental analysis, you will experience liquidation in future trading, reason is because the manipulation there is way too much.
Future trading is more like gambling, you are not wrong, but it is not gambling. Just that future traders needs to be careful, learn how to use technical analyses and also be able to use low leverage.
Assuming if a future trader is using 1x or 2x leverage for future trading, if he is only trading low rsik assets like bitcoin, it is very slim and hard for his asset to get liquidated, all he can experience is loss or profit, some people still believe in what they analysed, but analyses can fail, such people can be sentimental at times and the market will correct itself towards the position taken and they will make profit.
I am not saying future trading is easy but it is possible for traders (experts) to trade and their assets not get liquidated.
