I would add to Christian’s point that many respected regulators (e.g. FCA and ASIC) limit leverage to 1:30 for retail investors. They do this because very high or excessive leverage has led to traders incurring thumping losses. So as suggested, steering clear of high leverage is sensible, especially if you are new to trading.
Many brokers also offer flexible leverage where you can manually lower the amount used, and thus your risk exposure.
